Your first impression is - for pure aesthetics/attraction, should i weight more?

Depends: It all depends where you're starting out. As we age, we lose volume in our faces. For people like that sometimes a little extra weight can actually make you look younger. But we are not talking about gaining 20 lbs. Some of the older hollywood stars often had a "one pound a year after 60" to make your face look younger. Weight gain has to be balanced with healthy living.

Ur wt: 90 or 900 lbs: This is not a simple question and the answer is not a straightforward yes or no. There are several factors that will influence this decision.
