Forgetting how to walk!!!

Some adults, in the US, are forgetting how to walk by their own feet in 21^st century. Have you known that almost one third of the people have obesity issue in the US which leads the governments to spend lots of money on their health care? In the US, the healthy eatable and drinkable goods are so expensive while the unhealthy ones are very cheap and inexpensive. Asking more TAKS for such unhealthy goods like Coca-Cola or creamy sweets as well as increasing people knowledge might be helpful and reasonable to have more healthy society.
