I think its mandatory becuase at our age, we're going through hormonal changes and hella body changes. We're gaining weight, losing it and staying fit and healthy is mandatory to be able to maintain that. By gaining too much weight at a young age, you can cause many future health problems. don't get me wrong, every body is beautiful and everyone was born different but we just need that little bit of exercise to keep our blood pumping and keep up healthy.
Starvation, too much exercise, dizziness, fatigue, slow growth, brittle nails, etc
Approximately, at least 4,000 young people try smoking for the first time each day.
Hope this helps!!
