67 - Yes I can and I'm not an Obama either!
I can stand on one leg for 10-15 second and then get the leg wobbles. I can get out of bed in one go with no groans (yet), and I can put my socks on standing up (well most of the time lol).
I don't do any yoga or gym or swimming, just walking, fast (ish) pace every day and on the way back carry 5 + Kilos in my backpack with shopping. I make it my business to pass a shop on my walk as I can't walk aimlessly like in a prison yard, there has to be a focus!
Old age will catch up with me, but for now I'm happy enough with what I've got. I'll never be twenty again anyway so gotta be realistic.
