Go for it (with care). As the pounds came on, we lost our ability to participant in lots of things that we loved to do. If you feel your ready - then just do it.

I used to ride a unicycle and wind-surf. I still have all the wind-surfing gear in the garage. The last time I used it, it practically took hurricane force winds to get me going. I'm hoping that by the summer of 2015, I'll be the right size to give it another try. Hopefully, I'll remember how to put it all together.

BTW: My daughter took up unicycling, so my old Schwinn unicycle is getting used.
