Oh, is getting skinny a skill these days? :-)
Eh, where to vote for you!
Thanks for visiting my site, yes, it's mine. Hope you've enjoyed your reading.
In a team, you can have discussion, and get to know people with same interest or needs. If you want to lose weight, for example, you can set a goal 'lose x pounds in 2 months' or something like that. Other members of the team can support you or even help you when you need it. Other than that, it's just fun to get friends with same hobby or skill, right?
