Going for a walk.

What I've explained to my friends is that things could be free if you where willing to make them from scratch yourself. By buying the things that you do on a daily basis, you're basically paying other people to grow food or different items that you need on a daily basis, paying people to make things like cellphones or potato chips and even paying people to ship them to where you live from different locations around the world, which is why they're not free and why a lot of them are expensive.
air, water, walking. that's about it.
breathing. it's mostly free
Strange enough, in high school we had a few guys who taught getting one would be "cool" because it would be "proof" they got laid........
We were lead to believe so.
