New Plumber in the House is a post I wrote after (successfully!) fixing a toilet valve that wouldn't shut off. I'm not much of a plumber and don't intend to be at this stage of life, but I did feel good about that.
I don't know about teaching old dogs new tricks, but if you're an... um... older person like me, you can learn new things, too. As a matter of fact, the more new things we learn, the younger our brain stays, they say.
I guess I wouldn't want too young of a brain, butI doubt there's much danger in that.
