问题: Why can't many people keep healthy?

Many people struggle to stay healthy because they just don't have the time. With busy work schedules, it's hard to fit in exercise. Students also find it tough to balance studies and part-time jobs, leaving little room for health. Plus, when you're short on time, fast food becomes the go-to option because it's quick and convenient, even though it's not the healthiest choice.

A significant reason many people find it challenging to maintain their health is the lack of time. With demanding work schedules, carving out time for regular exercise becomes difficult. Students, too, face the challenge of juggling their academic responsibilities with part-time jobs, leaving minimal time for health-focused activities. Consequently, the convenience of fast food often wins out, as it fits into their tight schedules, despite its negative impact on health.
