This forum deals with a very popular niche. I can hardly think of anyone I know who is not interested in being healthy and fit. I believe you, too, have lots of friends who are interested in such things. Now, the question is, are you sharing this on Facebook? When you come across an interesting item on this forum, are you sharing it on Facebook?
I think if we all start doing this, it would serve two purposes. One, it will bring to our friends' notice, some useful information found in this forum. Two, our friends may join this forum and share their own information and thoughts about health and fitness. Win-win, right? What's there not to like.
