My grandfather tended a 2-acre yard for their ma and pa motel up until the age of 90. What did he do? He used a push mower - no self-propelled anything and was picking weeds by hand. He was in better shape at age 90 than a lot of 30 yr. olds are, simply by doing basic human movement every day - walking, bending/stretching, pushing around small machinery - and lots of it.

I use a gas mmower that must be pushed.
When I was about 22, I took an assignment out of the country. I dropped by my 90 year old grandfather’s farm to say good by and he took me to see his newly planted orchard!!
