Like You Were Dying

"How's it hit ya, when you get that kind of news. Man what do you do. And he says, I went sky divin', ''I went Rocky Mountain climbin', I went 2.7 seconds on a bull named Fu Manchu."

- Tim McGraw, "Live Like You Were Dying"

A character knows that the end is nigh. They're usually sick but sometimes doomed in another way. The character understandably angsts about it. They angst so much, that they can't make use of their remaining time. But then, they meet someone: A character who's equally doomed, a Love Interest or a happy innocent child. This person's attitude can be summed up with: "Yep, dying sucks, but life is fun anyway." The two become friends and have a lot of fun. The good, healthy, swimming-naked-in-the-sea-at-night sort of fun, not the waste-time-surfing-the-net sort naturally.

Usually no one gets healed, but before the movie or the character's end, the second character's attitude has rubbed off on the first one. Sometimes a character recovers or the diagnosis was wrong in the first place, then they decide to still make the most of their considerably elongated lifespan.

Sometimes the roles are reversed, and it's the dying person's winning attitude that rubs off on some loser that doesn't know how to live. The basic lesson is the same, though.

Compare with The Last Dance and You Don't Want to Die a Virgin, Do You?. Not to be confused with Like You Would Really Do It.

Anime and Manga

 * Katekyo Hitman Reborn! lives off this trope as if it were to die!!
 * I.e., the main character is given superpowers fueled by his 'dying will;' initially by shooting him in the head with special bullets that induce this level of sudden Heroic Willpower (and Shirt Disease), then steadily less violently and more intentionally, until he's able to switch into this mode at will, and it's more or less just a super mode which is on fire.
 * While not actually on the verge of death himself, due to a tragic accident during his childhood that claimed his parents and grandmother, Arihiko Inui was painfully aware that death could come at any moment. Luckily for him, he becomes friends with a certain Shiki Tohno, a boy who really was commonly on the verge of death when he was younger, but whose maturity and philosophical outlook were far beyond his years...
 * In the D.N.Angel manga it's found out that the people in family have short lifespans, and he doesn't have much longer to live. However, at the same time, he notes that Daisuke was the only person who gave him joy in life.
 * Macross Frontier plays with it some, uniquely in a way. . As you might have guessed from the wall of spoiler text, it's complicated, and this is the short version. Still, it's clear that Character Two was very important to Character One.

Film

 * The Bucket List
 * Stranger Than Fiction has a similar idea with a truly creative kind of doom.
 * The Timothy Dalton/Anthony Edwards movie Hawks. Two terminally ill friends decide to live as best they can for as long as their bodies hold out.
 * Basically the movie A Walk to Remember
 * The Bollywood movie Kal Ho Naa Ho
 * Harold and Maude - An Emo Teen who attends funerals and commits mock-suicide for fun gets into a relationship with a 79-year-old woman who is basically the septuagenarian equivalent of the Manic Pixie Dream Girl.
 * Dream With the Fishes, where a morose voyeur is saved from suicide by a happy-go-lucky fellow that is terminally ill and wants help living out a few fantasies before meeting his maker.
 * What so no one watched Last Holiday? Just me? Alright.
 * Can you blame 'em? I can't.
 * The 90's German movie Knockin On Heavens Door (yeah, like the song) is about two men with terminal diseases spending the last of their days enjoying some millions in cash from the mafia they got their hands on.
 * If we mean the same movie, then their original plan was just to go and see the Sea. Money just happened to appear bit later.
 * Joe Versus the Volcano has this as its plot. Joe has a decidedly mediocre life, with a mediocre job, but even his mediocrity is ruined by his massive hypcondria. When he is told that he really is dying, from a "brain fog" that has no detectable symptoms until it ultimately proves fatal, an eccentric millionarie offers to give him an all-expenses-paid trip to a tropical Pacific island where he will then sacrifice himself in a volcano in accordance with native tradition to secure the millionaire the mining rights for the island.
 * In El juego de la verdad, Ernesto is mistakenly told that he has three months to live. During a game of truth or dare, his friends convince him that he should do the things he's always wanted to do and assure him that they will go along with anything he says. The things he wants to do include skinnydipping and sleeping with his best friend's fiancee.
 * The film Scent of a Woman does this trope in both directions. Colonel Slade teaches poor, outcast prep student Charlie that you don't have to lie down and let other people's expectations of you determine your life. Charlie teaches the blind, bitter Colonel that you don't always have to spit in people's faces to make yourself important, helping others and sticking to your principles accomplishes the same thing. The Colonel stays blind, but is a little less bitter and Charlie accepts that he'll never be one of the rich White kids at his school, and is okay with that.
 * In L: Change the World, L spends the last week of his life taking care of two children, even holding a picnic for them while on the run.
 * In Short Time, Dabney Coleman plays an overly cautious, by the book cop who due to a mix-up is told he's terminally ill. He then discovers that his cop life insurance policy will only cover "professional damage" meaning he has to be killed in the line off duty. Wanting his wife and son to have the money, he decides to no longer play it safe, tosses "the book" out the window, and becomes the sort of risk-taking supercop who you only find in movies. Finally, after nearly twenty years of drudgery on the force, begins to believe that his life and his job means something.

Literature

 * Early in Remnants, when Mo'Steel rides The Pipe.
 * The entire premise of Deadline, in which the narrator knows he's dying but keeps it a secret from everyone, decides to not go through treatment and live the last year of his life as best he can. While all he seems to care about is getting a street named after Malcolm X, the book has a feel of "life is AWESOME!!" to it.
 * Valancy Stirling of Lucy Maud Montgomery's The Blue Castle (1926), making this one Older Than Television. Valancy gets a diagnosis of terminal heart disease, then uses her new-found remaining time on earth to live like a free spirit, talk back to her rude relatives, and fall in love.

Live Action TV

 * The premise of the very short-lived Sitcom Twenty Good Years starring John Lithgow and Jeffrey Tambor.
 * In one episode of Star Trek: Deep Space Nine, Quark gets diagnosed with an incurable and frequently fatal syndrome by a doctor on Ferenginar. He auctions off his vacuum-dessicated remains in traditional Ferengi fashion before he dies, but then it is revealed that the diagnosis was incorrect.
 * His initial response? "It means I get to sue Dr. (whoever) for malpractice!"
 * Subverted in an episode of House. Wilson finds out that he had earlier misdiagnosed a patient with terminal cancer. When telling the man that he is in fact perfectly healthy, he is surprised to find the man is outraged: knowing that he was going to die within six months had given the man real happiness for the first time in his life. He then promises to sue Wilson for malpractice.
 * Made funny when House gives the man the name of a good lawyer. Because he's House.
 * Played straight in a different episode. A young girl with terminal cancer who has an astonishing bravery and dedication to enjoying the little time she has left. Despite his best efforts as misanthropy, the girl's zest for life rubs of on House and he ends up buying a motorcycle.
 * In an episode of Scrubs made to parody sitcom cliches, one patient was found to only have 24 hours to live, and was taken out by the doctors to go through a list of adventures before he died. Then, at the end of the day they found out his chart had been switched with another patient, so he was not going to die, and the patient who was was antisemitic so no one cared about him.
 * Subverted in that
 * They had a separate episode with a subplot almost exactly identical to the House example above.
 * The Big C has Laura Linney's professor character diagnosed with terminal cancer, deciding not to tell her family (to spare them misery), and spending her last few months taking life by the balls. The first season of the show then thoroughly deconstructs this trope, as her actions look extremely bizarre to her family and only widen existing riffs, while not really bringing her a lot of joy.
 * During the third season of Supernatural, Dean knew he was going to die, as at the end of season two, he, and ended up with a year to live. So, he spent most of the season living it up whenever and however he could... at least until he got a taste of what would happen to him when he died, at which point he fought like Hell to survive.
 * In the Korean Series Scent Of a Woman, the lead is given six months to live. She creates her bucket list, including dinner with a pop star and the chance to fall in love.

Music

 * Pretty much the plot of the Tim McGraw song Live Like You Were Dying from the quote.
 * On a similar note, "One Day Left to Live" by Sammy Kershaw. The singer barely avoids a fatal accident, and decides that from then on, he will live like he's got one day left to live.
 * Don't forget "If Today Was Your Last Day" by Nickelback.
 * Also DC-10 by Audio Adrenaline. Although the cause of death is a bit more sudden and humorous than illness.

Theater

 * A "couples" example from RENT: Angel and Collins are the "live like you're dying" couple who get Roger to open up a little. Mimi, who is Roger's love interest, finishes the job despite a considerably rocky start with him.
 * "No Day But Today"?

Video Games

 * Final Fantasy IX: Played straight by Vivi, whose race has a very short lifespan. Averted by Kuja, who doesn't take the news of his pending demise very well...
 * In the Visual Novel Heart De Roommate
 * This happens to several characters in Tales of the Abyss, but some take it better than others...
 * Shadow Hearts: Covenant has a strange example.
 * Metal Gear Solid 4. The protagonist is not only extremely old,
 * Subverted in Jak II. The audience is made more aware of this than the characters, given that they're regularly bombarded by creepy voice overs from Baron Praxis's City-radios, which often serve as "Wanted Dead or Alive" adverts or handy little reminders to Jak that the Dark Eco in his body will eventually kill him and he's just delaying an inevitable and highly painful end when Praxis could make it so much faster and painless... It doesn't stop Jak, however, who doesn't so much plan to end his days happy as he does plan to gun the living bejeezus out of the Krimzon guard and seek his revenge against Praxis.

Webcomics

 * Examined by Bug, who shows that you need to plan your spending wisely while doing this.
 * Alisin from Fans! in early strips. Finding a cure was the first step of her Character Development from the hedonistic "Alisin" of the first two books to the "Ally" of the fifth and onward.
 * This is hinted to be the motivation of Larisa from Sandra and Woo, who's certainly diabetic, and also hiding some additional drug regimen from her friends.

Web Original

 * Kirk in The Gungan Council lives vicariously all the time due to having just a few more years to live.

Western Animation
"D.W.: "It's amazing what you can do in one day if you try real hard.""
 * The Simpsons, of course, has mocked this a few times, most notably with Homer believing that he would die after eating an improperly prepared poisonous fish.
 * In another episode Homer reads a self-help book that advises him to "Live each day like it was your last". Cut to Homer sitting on the curb sobbing "I don't want to die!"
 * Dexter's Lab had Dexter eating a comically oversized burrito and assuming that the gas cramps would make him explode, due to testing his hypothesis on a balloon.
 * In an episode of Arthur, D.W. and Binky each discover that they've eaten a "poisonous" green potato chip and become unlikely friends. Cue a montage them bodyboarding in a lake, watching 4th of July fireworks, carving jack-o-lanterns, and building a massive snow castle -- apparently "dying" for the better part of a year.


 * Goof Troop parodies that in the episode "Terminal Pete". Of course, it turns out to be a Mistaken for Dying near the end.
 * Then there was another episode with PJ doing this because he thinks his dad will kill him when he sees his report card.
 * In one episode of Camp Lazlo, Scoutmaster Lumpus steals a rare type cheese wheel from Raj because had never tried it. As it turns out, this particular type is extremely deadly and Lumpus only has a few minutes to live. He spends it doing everything he was not allowed to or unable to do in his life..
