What did Kenny “The Snake” Stabler look like at 38 years young?

My wife and I say that all the time. My grandmother looked "old" in her 50's and 60's back in the 1970's and 80's. My folks are now in their 70's and look like my grandparents did in their 50's. Maybe hair color? Or could be they just worked so much more outside. My grandad never bought a Tractor and farmed about 80 acres with a draft horse. That was in the 1960's-80's. My mom and her siblings had to pick cotton by hand with my grandparents back then. So I guess maybe the harder work aged people more. Or I guess it could me hitting 50 this year and me thinking everybody (including myself...lol) is looking younger these days. Lol
It could be a factor. But could be the life style back then too.
