Most of us realize we should take care of ourselves by eating right and exercising. At 20, our bodies may let us off the hook a bit if we do not eat right or skip some sessions at the gym. But at fifty, or seventy, it is much more important to make health a hobby.

And scientists are finding that everything is tied together. Of course, as we age we worry about our skin, belly fat, brains, and overall fitness. Changes that benefit one thing are likely to be good for our whole selves. On the other hand, damage we do to one system will harm the rest of us too.

Omega-3, for instance, is one of the so-called good oils. It has been demonstrated to help lower cholesterol, even with people who consumer quite a bit in their diets. This oil, one of the good fats, can also improve skin and hair. One natural substance can have an important positive impact on more than one system in our body.

We know that our metabolism and activity levels tend to decline as we age. But exercise can help boost it back up. It can also reduce many disease risks that increase as we get older. And of course, some moderate exercise will help us look better, and it can also be a great way to reduce tension and anxiety.

Experts advise us to fit in at least two hours of exercise every week. This is not really that much, and it can be done with 20 minutes of exercise done 6 times a week. We do not have to train like marathon runners either. A brisk walk or turn on an indoor bike can benefit us. It is just important to stick to it.

Watch the bad fats and bad carbs too. A huge steak dinner with fries should not be on the menu every nigh. Try to replace red meat with fish a few times a week. If you must go out for a steak, try to order a smaller portion, and then make sure you eat it with a nice salad and some fruit. Science has demonstrated that some good food can help our bodies deal with some of the less healthy food once in awhile.
