If you don't mind me asking, is there a reason why it's 7 minutes and not, say, 5 or 10?





I actually tried both. 10 felt too long and approaching the territory of wasting more time than I wanted. 5 felt like it wasn’t long enough. I guess 7 was just right for me.

why 5 or 10 rather than 7, hm?

Fair point. I think humans having (usually) 5 fingers on each hand makes it familiar to us.

What about -∞?
