A caveat, before I start: I'm a night person and sensitive to bright light. I don't smoke and I don't like cats.
I've been around the world. I've gone through (emotional) death and rebirth many times as events caused drastic changes in my persona. I look back at the man I remember I once was; sometimes wondering what happened to him and why he's gone, other times bidding good riddance.
I sometimes wither, but mostly I grow.
I have become concerned with my health and the types of food I eat and I have begun exercising again to get back into shape. My perfect match would share these feelings and desires, but has the intelligence to understand why. Someone who never thinks that they're too grown to learn any more, who hasn't lost their curiosity, and who is always willing to learn or experience something new.
I am a great many things, and could probably go on for a bit, but these are my words; and because these can only be words until you know me, I will save them for when you do. Of course by then there will be no more need to say them. :)
