Those photos were a long time ago,
Back then....people, society, had no idea that bad health exists:
They would eat as much bacon and butter as they want.
Consume as much liquor and smokes as they want.
Eat as much salty and canned foods as they want.
Get as much sun as they want.
Vitamins, minerals and supplements virtually didn't exist then.
I'm sure the tap water wasn't as clean and pure.
Smog and dirty air existed from cars and factories.
No one knew the benefits of exercising.
All of these elements and variables can greatly, greatly, age a person.
