Back in the day, when I was transitioning from "gunfighter/40MM Grenade launcher" the extra 9 canteen pouches full of 40MM grenades & ammo made for running/swimming around VN mangrove forests all day & night adequate arm strength tuna fishing strength when I came home to SDiego and my 2nd hobby - Tuna fishing. But as I aged and more & more assignments became advisory to ice cream "baskin robbins" loving Admirals I learned what "Workplacesafety and Bob311 discovered, middle aged guys get hard (all over) with rowing machines. The really hard part on all of those 18 deployments (over 30yrs) was America's big tobacco giants used to send us "free cigarettes" and we all know the satisfaction of a cold beer, a lucky strike cigarette and a beautiful Filippino chick sitting on your knee. Best solution came 39 yrs later when I quit drinking & smoking and married the Hot Filippina chick. So at 81 still married to the "LBFM", 5'8", 210lbs, and with some help from above hope to see "ya all" next 2023 when offshore warms up and we once again startanother season chasing that badass of all badasses: El Tuna. HooYah!
