Perspective
Today I carried a couple of gallon containers of water up a flight of stairs, and it was a bit of an effort. A gallon of water weighs a little over 8 pounds.
Then I realized that before I lost my weight (130 pounds), I was carrying the equivalent of 15 gallons of water 24/7!
Another analogy: last winter I struggled to lift a 40 pound bag of bird seed into the back of my SUV. I used to be “wearing” three of them!
No wonder I used to dread physical activity. What a joy basic mobility has turned out to be.
