Re:Exercise 'keeps the mind sharp' in over-50s, study finds by grecy on Tuesday April 25, 2017 @04:48AM (#14191793)
The guy who ran my white water raft guide course was 74.

He did a backflip out of the raft in a 3+ rapid, into a glacier melt river North of 60. He laughed when I was given control of the raft for the first time and I flipped it with him and five others in it within 30 seconds.

I'm willing to bet he will still be having a ball at age 80.

in your 70s you age much faster than you think. 5 years do a lot more damage than you expect from 75 to 80.
