I just turned 76 last month. Been in pretty good health overall but
I am noticing my balance is not as good as it used to be and that
I don't recover from stubbing my toe on obstacles as well as I used
to. I think it would be difficult now for me to go forward and try to
wrestle down a flapping jib with the boat bouncing around. I don't think
things will improve as I get older, but I can only speak from my own
experience, your mileage may vary. I am sure there are still some 80 year
olds out there that can leap over tall buildings with a single bound.
My only advice is to do it as soon as you can even if you have to stretch a bit, FWIW, my 2 cents worth.
