Years ago my next door neighbor was about 80+ years old - one of the first Eastern Airline pilots - guy weighed about 100lbs and he had a tiny dog that would nearly knock him over pulling on the leash.
Herb (his wife was Ginger and we nicknamed them the spices).
In any case, he had the giant sword he had picked up in Japan during his youth and would walk around his yard stabbing the mole holes. I swear that sword was heavier than him, but he wielded it against the moles like a samurai decapitating an imperial army officer.
The guy flew his private plane out of a grass strip aerodrome to the very end. Said it was the only way to land (hot air on the grass makes the plane float).
Cheers Herb!
