I thought about going to the YMCA today to watch my granddaughter and her mom at work on Anah's science fair project. It's quite the deal involving folks walking on treadmills and recording their weight, BP, oxygen saturation, target heart rate, recovery time etc. I've forgotten the term they use, it's not hypothesis though, but another word describing what they are trying to prove. I think the premise has something to do with the effect of exercise on fitness. Obviously I haven't been listening closely enough when they explain it to me. Erin told me I would probably be bored so I just didn't go there.
