Thorn bird,
I've seen people from 60 to 65 years of age that are built like a horse, still working on building sites with a jack hammer,
can still outperform any person in their 20's, 30's, 40's in term of physical agility and strength.
I've also seen a 70 year old man doing 100 kg bench press in the gym, stronger than anyone in their 20's or 30's.
Not sure which age level you're at, but if the health is there and the drive, you can be an instructor and go to U.S.
Recommend to get to gde 2 instructor level prior to applying.
Don't forget last weekend a man at 104 years of age, travelled to Switzerland to volunteer for euthanasia, there was nothing
wrong with him.
Life doesn't stop at 60 or 70, people work to 75.
