i noticed my decline at 50, (others probably noticed it 40-onward..lol .) at 57 all i see is hooded eyes, crepey decolletage, emerging jowls, thinning hair;
i have noticed my 'peers' with similar, plus the puckered lip lines or 11 lines between the brows, (we are all easy-going, not health and fitness types) and one (smoker) has very dry-looking criss cross lines across her cheeks and noticeable droopy skin
1 'peer' who is 60, looks 40- slim, blond, firm-jaw , a few laughter lines, but slim and fit...not sure if its her healthy diet, no caffiene, little alcohol, regular 5k running, or her toy boy!!
also in our group we have one 60 yr old, red-head, fine, smooth skin, size 8, thick hair, bright eyes, never smoked but enjoys a drink,doesn't limit her diet, looks fab
