Wow, PGM, great genetics indeed!
Forgot to add, one other secret to my 70 year old wrinkleless skin may be that I use the Vaseline brand aloe liquid/cream. I think aloe is a miracle drug---what it does for sunburn is just incredible, but it also helps with healing the skin in general. Anything with lanolin is great, too. For a while I had something with lanolin AND aloe and I was in heaven, but of course that is gone now. So, in order, I wash my face with Camay in the am, add Oil of Olay, then the Vaseline, then the Oil of Olay eye cream (the only expensive component). At night I just wipe the make up off (in addition to above I use some eye liner and shadow, mostly rubbed off, and a little foundation/powder where I have some rosecea) with water on a tissue and apply the same cream regime. I think it mostly works because it keeps the skin from drying out.
