I used to have a very polite intro to my profile which was not attracting anyone so here's my new one LOL:

Fully sick guy with some grey hairs and kick-ass attitude who does not want to meet anyone for anything other than a conversation.

There - that should do it!

Oh yeah, and one more thing...what's with all of those bloody profiles that say "no single men"? Single, I'm not single, I'm a divorced man - I totally hate seeing that on people's profiles!
