I am curious if anyone knows -- pug mentioned the fact if you stop for a few weeks for whatever reason, you lose a lot of the gains you had from lifting.
What you're talking about are two different components of strength training. One of the factors in getting stronger is neural; your brain and nerves get better at activating the muscles. The second factor is muscle gain; more muscle can move more weight.
What you lose when you take a long time off from lifting is the neural component. It's the opposite of Pavel's Grease The Groove, where you lift multiple times a day every day (to "grease" the neural groove). You kind of get "out of practice" and find you aren't as strong as you were before you took time off. However, you can get this kind of strength back relatively quickly once you start lifting again. Your muscles don't just disintegrate after a couple weeks of not pushing their limits.
In fact, one lifting system (Hypertrophy Specific Training) is pretty much a simple linear periodization plan that incorporates a 2 week deload period where you just do very light exercise in order to decondition your muscles. When you start lifting again, your body is deconditioned enough to respond to the light weights that normally wouldn't elicit any hypertrophy.
But when you guys talk about old people wasting away, is it a known fact that if someone did strength training for most of their life, let's say, and then for the last 10 years could not anymore, do they have gains in their muscles and bones that continue to help them during those 10 years?
Yes, that is a known fact. Strength training increases a lot of health markers, especially muscle mass and bone density, which don't go away immediately when one stops training. So during your hypothetical's 10 sedentary years, they'll still have those gains for at least some of them. Which they wouldn't have had if they hadn't done strength training.
"You haven't, I suppose, ever mixed with politicians at close quarters. They're awful. I think some of these must have been the dregs anyhow, but I've discovered, what previously I didn't believe possible, that politicians behave in private life and say exactly the same things as they do in public. Their stupidity is inhuman.
