Actually Soz, 35 isn't a bad age for a lot of us. By 35 we are pretty well past the raging hormones and roller coaster emotions, we have some significant life experiences under out belts, and usually a more realistic view of the world. It's usually in our mid 30's that we first start feeling all grown up, at least most of the time, even when we don't know what we want to be yet.
Now it has been quite awhile since I've seen 35, and I have had even more life changing life experiences since then, but I honestly can't say it feels any different now than it did then. I think most of the same things are important to me and the same kinds of things make me happy, excited, angry etc.
I don't have the stamina I had at 35 and I hate that. But otherwise, that feels about right.
