“The earth is like a big treadmill.”

Sam remarked about the earth treadmill tonight while we were reading up on fever and how the body manages homeostasis unless challenged. The challenge might be an infection – the fever denatures the viral capsid coating so it can’t take over your cell’s machinery to churn out more viruses. This was particularly relevant because Sam had a fever today so was home from school, lounging. I love sick days, except I feel bad for the kiddos if they are really feeling awful. Thankfully it’s just another low fever so hopefully it will be a short course for them.

Back to the treadmill. While reading the Biology book tonight about homeostasis and fever, we saw a picture of a ghost crab on a treadmill! The ghost crabs are our little beach friends so we were curious to see what he was doing in a tank on a treadmill. The scientists were measuring metabolic output. So I explained what a treadmill is – a sheet covering two cylinders that spin around and you have to keep up on it or you fall off (like I did in ancient times past while enrolled in a running study – I closed my eyes while running on a treadmill hooked up to all kinds of equipment because I was bored  – apparently that is not a good idea on a treadmill!). Sam says “The earth is like a big treadmill, except going really fast.” I agree. Earth is spinning extra fast I think right now. I just can’t seem to keep up! Thank goodness for my mom running out for emergency supplies of all sorts – she is expecting a call around 7pm every night I think 🙂
