You become immortal and are forced to watch all your friends and loved ones age and die so that all you have to write for the rest of infinity are angsty poems the emo kids will steal and post on Tumblr as their own.

Also, you would live long enough to witness the death of the sun, causing Earth to be incinerated (youth and health won't save your from that). If you can somehow manage to escape to space, then you are now immortal but mostly alone in the quiet sky, traumatized from losing most everything you knew and loved so that you go very mentally insane drifting through the endless void.

I wish I could find all of the games and toys I mysteriously lost.
