Why have I put on 5lbs surrounded by just a couple of weeks?

I read the article, but it doesn't read aloud that scientists can tell whether you're have sex or not. It mentions promiscutity, or sleeping around, tends to run surrounded by people who are downcast agressive. It has nought to do with whether you can share if someone is having sex or not, a moment ago personality types that tend to be promiscuous.
