Mark,
I know exactly how you feel, I'm going through the same thing right now. It's nice to finally be able to talk to someone who I can relate to. I was diagnosed about a year ago, and still appear 'normal'. I havn't told most of my friends about it, and nobody even notices anything is wrong.
However, like you said even some of the simplest things become difficult, or impossible. Ice and snow are a big problem for me now. I can barely walk on it at all, and where I live we've got snow about 4-5 months of the year.
One of the first things I noticed and continues to be a problem is bending at the waist to do things like washing my hands at a low sink. Has anyone else had a similar problem? I feel like I'm going to fall forward, and usually need to hold myself with one arm and wash one hand at a time. I've noticed this years before I had any other noticable problems.
I sometimes wonder if it would be easier if most of the people around me knew the limitations I had, but its not an easy topic to bring up with friends. But aside from all that, I'm also quite happy and try not to let the limitations get in the way.
