What is it like to be 80 years old?

When is the last time you talked to an 80 year old? Would you even consider asking this question to an 80 year old in real life? Why try to research this question on HN where the average age is close to 25? What do 25 year old hackers know about aging? Oh sure, I have no doubt they assume they know something about everything but I really think you're barking up the wrong tree and need to go outside and, you know, talk to people.

Even knowing how people would compare their level of self-awareness at 40 to what it was when they were 20 would be interesting.

There are probably quite a few people here that are 40+ years old.
