I worked out harder than usual yesterday. Today I'm a bit sore where I've never really been sore before, which tells me I hit on some neglected spots. And I've got some tendintis going on in my left achilles, going to have to deal with that somehow. But it's working. You know, not too long ago I had to rely on a cane. Now I don't. I'm stronger and have somewhat better (although still not great) balance.
