What's the difference between past lives? Answer in English. Thank you.

Compared with 20 years ago, our living standard today is too high. Twenty years ago, children used to go to school by bike, but now they are taken away by car. Twenty years ago, they often took homemade sandwiches to school. Now they can buy junk food. Twenty years ago, we didn't have a game machine, so they played football or climbed trees. We kill our children with kindness and spoil them.

Exercise more and eat less junk food = healthy children.
