Smoking and drinking are known to be major factors, yet I knew many members of religious communities who were very strict about having none of that and they still showed their age earlier.
There was earlier and more childbirth, but that doesn't account for the men.
Some of the men were outdoor workers like farmers, and they definitely showed earlier aging.
I think diet and environment must be a factor. I've read medical literature on the prevalence of toxic chemicals in foods, consumer products, and industrial processes before WW2. My impression of family histories is that major physical ailments were more common in that era.
