Stretch Marks?

[shintao]

I was thinking women gain a lot of weight in post-era aging, so require rigerous exercise and starving to beat the bulg & land of stretch marks. What environmental reason would there be for that to occur in the life of a women towards the later years?

I doubt they did.
American diet certainly would be a culprit, as well as sedintary lifestyles.
