Let's see......something I know about! Stretch marks!
Have them on my breasts from nursing my children and of course on my tummy from being pregnant with them......I call them my children's life lines.....for their nourishment came from within while they were inside of me and from my breasts once born. Seems to me there are far too many airbrushes at work when we see pictures in magazines and such......not too many don't have stretch marks!!! Just my two cents worth lol.
