Very soon I will be celebrating another birthday, #58. My sister went ahead and bought me an early present. A Pulse Oximeter. You clip it on your finger and in a few seconds it gives you your heart rate and oxygen level.

This is about one of the best presents I've ever gotten. It's like having your own little amusement park right on your finger. I just set around with it clipped on my finger watching my heart rate. Some times I hold my breath to watch it change. Some times I get up and walk around to make it go faster. It's just all kinds of fun.

Thanks Janie for my favorite new device.
