It’s a great excuse for our own laziness
We all like to put things off until the next day, month, or year. People who are overweight like to postpone their plans until the next life — when they are thin and slim. It’s a great excuse: "I want to learn how to dance, but I can’t because I’m overweight. When I lose weight, then I will start training every day, and I will become the star of all the parties. You’ll all be jealous! But so far, thank goodness, I don’t need to train so hard. So I’ll just jog a bit in the evening and go to bed with a peaceful mind."
