Which situation I should use "Also" and "Too"? I thank if you could give any exemples

healthy style When I see some seniors doing excercises, like running, swimming, biking and others, I feel good and I wish to arrive that same way at that age. But for turn it possible we need to take a path with discipline and determination, we need to know what we want and to be able to pay the price. We don’t have many choices, we can do nothing and cheer for the best, maybe the worst happens, fifty fifty probabilities, or we can do something and improve the odds in our favor. I choosed the second opcion. But it is important to do this with caring, because we can hurt our body. Let’s Imagine the following situation. You are driving your car for the city, up and down the streets, accelerating engine in wrong way on wrong gear. How long do you think this car will ride until it fails? Not much. But in this case you can let the car in a mechanic and fix what is broken, you’ll have learned the lesson and will not repeat the same wrong. It is similar with our body, but in this case we don’t have the luxury of making mistakes with our body, you can’t fix your body like you do with your car. Maybe you can treat an illness, but it will take a long time, maybe years, spending a lot of money, and probably you’ll never more will be as before. So, first of all, Be smart and look for technical support, find a specialized professional and do exercises the way he teaches you. This is a long-term investment; avoid forcing your body to achieve fast results, remember of the car. Of course, there are many people doing exercises for themselves, but there are so many possibilities of they hurt their bodies when they are exercising. You can do it alone, anywhere, but that the odds tend to better results when you do this with a partner. Do exercises is a critical decision, because it is for entire life, it is hard but the rewards worthwhile. So let’s put it in our routine and make this a moment of pleasure.
