Lol, as I am getting old I care less and less whether I look happy and welcoming :). I am increasingly less and less concerned about projecting socially expected emotions when I don't have them.
Through, I do care also less about how I look, through I am trying to force myself to care bit more.
Maybe it's a bell curve - when we do reach 70 we'll not care about either, much as we did as toddlers!
funny i read this on the chicago subway and there was an ad right in front of me that 65% of males "suffer" from hairloss and there is a "treatment" available in form of monthly delivery.
Being male is now a disease.
Social pressure is so strong! I don't know if you are a woman or not but from my perspective (as a woman) I am truly grateful for each year I live, as I become less and less worried about my appearance in detail, and more about the expression on my face and my body language - how happy and welcoming I look when I greet people. This knowledge wasn't obvious as a young woman.
