A healthy lifestyle.

A healthy lifestyle is one that allows you to realize all your potential, to be disease-free, and to be happy. This ideal definition makes me wonder if in these days we can have one... Even more I wonder if it was possible to have it in the past, and if it will be possible in the future.
However, we have to think that it IS possible, but... What we must do to have it? How much is it? How long it takes?

Since we know a healthy lifestyle involves having a healthy body and mind, we can propose that some features or elements of it are the followings.

Eating healthy and palatable food, to have that things that your body needs. Eating of all kinds of food.  How often? Four times a day, and a mid-morning snack. Take care specially not to eat too much salt and fats. Include five portions of vegetables per day, and legumes twice a week, and so on...

Doing a lot of physical excercise. This is good for your cardiovascular system to your brain and other body's systems, as much as for your body's appearance.

Laughing enough, everytime, of everything and with everyone. Of course, always with respect.

Drinking at least two liters of water per day.

Reading a lot, to excersise your brain.

And, in the end, doing (almost) everything you can do with both your body and your mind, but avoiding excess. Except with love: you love in excess. You love everybody.
