There are a few on the BBoard in much worse conditions than mine, and I would certainly like to read more of their efforts, in private if need be.
My musical endurance is returning slowly because I only practice about 30 minutes a day on average.
The joke of my strength is precisely in that: I'm now a weak-link! This is in part because I spent the last year trusting my IMS/physiotherapy and used my free time for recording and blogging instead of fitness..... well, people with underlying problems need to concentrate more on fitness than others just to keep in "normal" shape.
I had actually started planning for IDRS 2012 convention when I realized how ridiculously rickety I am. So I have decided it would be best for my musical practice to strengthen up a bit instead.
