Yeah, I have seen the article before. Grip strength as a measure of manliness. lol
But if I allow that college males are physically weaker now than 50 years ago (it would be an average, of course, since our athletes are bigger, faster, & stronger), the question would be a matter of which skills and attributes matter in today's world.
A man from 50 years ago might have a stronger grip. How is he at computer skills? Can he work a smartphone? Can he manage a business that is now global and requires instant action?
And more importantly, will the man treat women as property or as equals in a relationship? Will he insist on beating up queers, or will he live & let live? Maybe he can't build a porch or rebuild the engine on the family car. But he can create animation, spreadsheets, or a multitude of other skills that help him make a living and pay others to perform manual labor tasks for him. So the newer man has more time to spend teaching his kids how to be quality people. He will have more time to spend with his love.
This idea that a man who is not physically stronger and is violent is pure bullshit. In the past we were stronger because we had to be. It is no longer a requirement in today's world. If you WANT to be strong, there has never been a better time. Exercise systems, nutrition and training have never been better. But that is now a choice a person can make, not a survival requirement.
