I have slightly crepey décolletage now and also some cellulite on my upper arms (only had it on lower body before).
I notice when people (women moreso) look at me now in summer tops that their eyes are drawn there, or they do a double take, as I always had such nice arms before. However, as a psychologist I notice they are then much warmer towards me, as if you look really good the opposite can happen, so perhaps it's not all bad!
