I totally get where u are coming from, I am 59 and I believe it is the age that is a factor in this.

I know for myself I am looking back at my life, and looking at what I accomplished and what I didn't. Sometimes with regret, sometimes not.

So finding people on facebook that accomplished some of my goals, or did things I never did and never will gives me a jealous, and envious feeling.

I just feel like as we grow older this will become more of a factor.
