The dental hygienist this morning asked me what kind of toothbrush I use. I told her I use some battery operated thing that spins. My kids have similar toothbrushes, only James' is Superman themed and Michelle's is in the shape of a princess. Both require batteries and both spin as they brush.
When I was young, my toothbrush was just a toothbrush. It worked right out of the box, no batteries or charging required. It didn't come with some funky theme, it came in a colour; blue or green or perhaps red. That's as wild as it got.
I'm thinking about going retro and returning to the simpler days when a toothbrush was just a toothbrush. The one I got from the dentist's office today is blue and white, just like my hockey team.
