It is better to be rich and healthy. I think to be or become rich is easier.
Lost money can be restored, while lost health is sometimes too difficult
to find again. There are lots of good reasons to keep active: your health
will be better, you'll have more energy, you'll feel more relaxed, and
less stressed! These are the most evident reasons for having healthy life.
People who understand it take care of their health.
'If you don't smoke you, perhaps, won't live longer but your life will
be healthier', my grandfather often says. He used to smoke for many
years but gave up about 20 years ago. Bad habits. They ruin your health.
Drugs, smoking, alcohol, overeating, sedentary lifestyle are the main
enemies of health. To be fit and healthy you should do sport or physical
exercises, keep to a healthy diet and never take drugs, alcohol or smoke.
When I speak about diet I mean that you can eat what you want but
remember how much and when. As for sport I think that professional
sport can be harmful too, but if you play sport games for pleasure it does
you only good.
I can say that my lifestyle is healthy. I go in for sport. My sport is
swimming, I train three times a week and take part in competitions. My
friends go in for sport too. They play volleyball, basketball and tennis.
My friends and I don't have pernicious habits but sometimes have one
extra cake or some coke or chips. One can't be ideal you know. Сократите текст очень срочно
