if it's ur mom, tell her not to worry. she's very calm looking. that's the best u can do for age. to be content and satisfied. i think she looks very young. she takes care of herself. u can tell when people do and when they don't.
her skin is really really nice. that is a big sign of age - when u start losing moisture - u just have to up the moisturizer. i like to be outside a lot - so instead of using what i did in my 20's and 30's - i use deep moisturizers. also, diet and exercise make u feel and look younger.
of course, for women - it's hormones more than men in ur 40's. but, surprisingly - i think when u exercise a lot (which i've tried to do) it delays the bad effects or negates them of menopause. u might be feeling bad once in awhile - but not every day. i think a woman should keep a diary and note patterns. what's good, also, i think - is when u have someone to love and someone who loves u. maybe all ur mom needs is a hug sometimes. i love it when my kids hug me. and, when my husband does for any or no reason. it's like filling ur gas tank. women get depressed when they do so much for a family and sometimes feel like they are invisible or something. just do something nice for her (as u already do) once in awhile - or, say something nice - or take her to get her hair done or nails done. my husband is really sweet - because he always asks how i'm feeling. and, even if i say 'terrible - or tired' - he's always trying to make things better. just the fact that he cares makes me feel better. flowers are nice, too.
