This thread is quite morbid so i apologize in advance.
A few days ago i was having a conversation with my girlfriend in which she mentioned in passing that she's signed up to donate her organs after her death. I was quite surprised because she mentioned it like it was no big deal. I asked her which organs. She said "everything". Heart, lungs, kidneys, liver, corneas, marrow, skin.
Then it hit me... i thought i'd faced my own mortality and wasn't bothered by it. But then i really started to think about it. One day i wont be here. My body will still be there, but it wont be me. Life will go on, people will still wake up and go to work, go the pub, marry, haves kids etc but i wont be around.
Then i started to think "should i donate my organs too?". I'd have no need for them. It wouldn't make sense to cremate my entire body if organs can be used to improve or save lives. I read online that a single person is capable of improving the lives of 50 people. 50! So i decided i'd do it. I've signed up.
The more i think about it, for me personally, there's no reason not to. My parents often joked that i was "an accident" - so if you think about it i wasn't supposed to be born in the first place. If any good can come of my eventual death i'd like to to be saving the life of another person.
Granted, It's not nice thinking about it. But i'm glad the subject came up and forced me to think of it.
