Think back to your college days, the good old days when life was easy. Stay up all night partying or even studying? No problem. Eat pizza every night and plow through entire bags of potato chips nonstop. Hey, no sweat. You were a lean (苗条的), mean, and also young machine.
But ... then stuff happens. You graduate, get a job, get married, have kids, and around the age of thirty-five you’re no longer so young and so lean. In fact, you’ve added a few pounds around the middle. And with each passing year you seem to put on another pound or two. By the time you’ve hit your mid-forties you may find yourself looking into the mirror and wondering, “What happened to the slim, young Adonis (希腊神话中的美少年)?”
How did this happen? Around the age of thirty-five or so your metabolism (新陈代谢) may start to slow down. Plus, you are likely to lose muscle mass （肌肉质量）, which slows your metabolism even more. The slower your metabolism, the slower the rate at which your body burns calories. So even if you’re eating less than you used to, you’ll start gaining weight.
But that you’re not a spring chicken （年轻人） anymore doesn’t mean that you have to get fat. In fact, the antidote (矫正方法) is pretty simple: exercise and eat less. Lifting weights or otherwise regularly working your muscles will add or at least keep muscle mass, which will help keep your metabolism.
So maybe you can’t stay young forever, but you can stay slim.
