Mac, I'm the last person to criticise someone over significant age gaps, my own long term relationship is such. However, you did write that you were intimidated by the active nature of some of the profiles - if you are wanting to date women in younger bracket (previously you stated 35+) then they will likely have active lives as long as they are healthy. All relationships are made of compromise of some sort, it's true enough not all active types will expect you to be the same, but it may be a consideration for others.

I don't think anyone called you a 'loser', that would be very cruel particularly as you have come here seeking advice. Of course we should all be aware that people posting here write about only a fraction of their lives and we should not make assumptions, your last post is a timely reminder of that.
