I think that age as a number is not nearly as important as health. You can be in poor health and be pretty miserable at 40 or 50. If you're in good health, you can enjoy things into your 80s.
Experimental science is fascinating, but I don't want to do it. I want other people to do it, and I'll read about it.
I tend to get comfortable with the dialogue and find out who the person is in the script and try to hit that. People are sort of independent of their occupations and their pastimes. You don't play a politician or a fireman or a cowboy - you just play a person.
