But if we are all doomed to a brief life followed by eternal nothingness, what's the point of, say, balancing a check book or bothering to wash your pits?

Just because we all die someday doesn't mean you should completely stop living. Use the time you've got to really make yourself happy. That, my friend, is what it's about.

Should I be freaked out that you just spoke to me?

Nope, but you might want to get the dosage on your meds upped a notch or two.
