A unit of time is constant. 30 minutes is always 30 minutes. But is it?
My wife and I cycle the same routes all the time. We leave our house and cycle to various destinations south. It takes 1 to 1 1/2 hours to get there. We drive from our house to the same destinations and it seems to take forever even though we are on a freeway going 65 mph. We comment all the time how long and far it is to drive. But on the bike, time seems to get warped in some way. It seems to speed up. It feels like we just leave the house and we arrive. Albert may disagree.
Does anyone else feel this way?
