A long-range view of things

But when I think about it, having the kind of body that puts on weight easily was perhaps a blessing in disguise. In other words, if I don't want to gain weight I have to work out hard every day, watch what I eat, and cut down on indulgences. Life can be tough, but as long as you don't stint on the effort, your metabolism will greatly improve with these habits, and you'll end up much healthier, not to mention stronger. To a certain extent, you can even slow down the effects of aging. But people who naturally keep the weight off no matter what don't need to exercise or watch their diet in order to stay trim. There can't be many of them who would go out of their way to take these troublesome measures when they don't need to. Which is why, in many cases, their physical strength deteriorates as they age. If you don't exercise, your muscles will naturally weaken, as will your bones. Some of my readers may be the kind of people who easily gain weight, but the only way to understand what's really fair is to take the long-range view of things. For the reasons I give above, I think this kind of physical nuisance should be viewed in a positive way, as a blessing. We should consider ourselves lucky that the red light is so clearly visible. Of course, it's not always easy to see things this way.
