It's 100% worth it to combat ills of aging (declining mood, physical performance)
Based on some of the studies I've been reading, I'm not so sure about that. There are definitely benefits to bone density and libido, but it doesn't seem to actually improve mood or general physical performance, and it definitely increases heart attack and stroke risk with increased arterial plaque buildup. In most cases, elderly men would be much better served by adopting regular exercise habits, which actually does improve mood, movement, libido, bone density, AND cardiovascular risk factors.
