Flying airplanes are perfectly fine for older people, but for me, if I do ever end up still flying til I'm old. When I hit 60, I'm going to walk into TC, give them my license, and end it there. Been there done that. Don't need to start slipping up or thinking that since I've flown for 40 years, I won't ever make mistakes anymore. If I want to fly, I'll go up with an instructor or a friend. But I don't want to die flying.
