I heard this a week back and it was thought-provoking in a useless way: Satan gifts you with infinite paper, a pen with infinite ink, and infinite life. The ONLY thing he asks in return is this: the first day, write the number "1" with the infinite pen on the infinite paper. Every day after, write the next number (i.e., write "2" on day 2, "3" on day 3, etc.). As long as you do this, you are free to enjoy your infinite life doing whatever you want. Sounds great, except, Spoiler there will come a day when there won't be enough time in that day to write your next number.
You would probably get bored before that happens. Writing down 10 numbers takes like 5 seconds (I reckon we can all agree it's not time-consuming, as it is a matter of seconds). This means you could live slightly more than 27397 years. 11 numbers would be around 273973 years. You're more likely to forget writing the number down and if you do, you won't realize it because you'll be dead.
