The older you are the less chance you have of finding anyone. I once contacted a chap who I sat oposite to in the Orderly Room where we both worked for a time. He couldn't remember me but I found out that he was suffering from dementia and that was about ten years ago. Make you wonder as you are obviously pondering whether it's worth it. I've been on so many sites I've lost count but that result was typical - I do have one solid result with a chap who used to be a Corporal storeman - we used to fall out a lot back then! Ah well - times change!
