Sometimes when I have a lot of free time I am visiting online services where people ask various questions they want answered. I don´t know if you have ever seen them. Sometimes you can find interesting information there but not always. There is also a group of people posting stupid replies that are not worth reading. It is easy to notice them because when you type some question into the search engine you usually get the first reply that is part of such online service as I have mentioned. Anyway, when have some time I am posting replies there when I am able to help people. Then those people rate those answers depending on the fact if it helped them or not. Recently someone wanted to know why would anyone want to gain mass. As I used to workout at gym a lot and I have heard a lot about different supplements I was able to answer it. When you gain mass you are able to build muscles easier. That is very important for people working out to get effects as fast as possible. Fromm what I have seen my answer was helpful and it was rated high. I feel happy that I am able to help others. What is even more attracting in such help is the fact that it doesn´t cost me anything but time.
