T-Rex: If you learn a new skill as a kid, great! You got a whole lifetime to benefit from THAT little self-improvement!

T-Rex: But you have less time to enjoy every new skill you learn!

T-Rex: And this reaches the other extreme, where any skill you learn at the end of your life is completely useless, since the next thing you do is FRIGGIN' DIE. Therefore, there are diminishing returns on learning and at a certain point it's unprofitable and we should all just stop.

Utahraptor: By that logic, there's diminishing returns on everything!

Utahraptor: But if you're satisfied with self-improvement, you don't NEED to use a skill to enjoy it - or, in your terms, to profit from it! We should all stay engaged in our world until the very second we die, IF NOT LATER.
T-Rex: By later, do you mean as ghosts?

Off panel: Yes. I think ghosts should go to adult learning courses instead of smashing plates or sliming people.
T-Rex: Oh damn!
Off panel: What?
T-Rex: ...Hah hah, I can feel my brain reconfiguring itself to endorse this amazing new opinion??
