Hey Don, but there was a time when some of those other injuries might have stopped you. So really, you have trained your heart to deal with that level of injury and pain.
Now, you could let me take a bokken to your ankle to see if you can keep fighting afterward....and then we'll know...
But I think I'd better have something more than a bokken handy...just in case your heart has grown...
That, or a REALLY good pair of track shoes...
Best,
Ron
