Coffee grinder, $10

I have to be forced into exercise to do it. And since I’m not about to pay someone to force  me, I just have to force myself. I sometimes walk into town to pick up the girls from school. It’s a 5km walk, and once I’m halfway I can’t turn back because the girls will be waiting. But walking doesn’t do much for my upper body, so I stopped buying ground coffee and started buying whole coffee beans. This is the only coffee grinder in the house, so even if I want to forego my five-minute upper-body workout, I can’t forego my morning coffee (it goes hand-in-hand with the Nicabate) so what choice do I have but to stick it out?
