Another benefit of giving is freedom. It's a matter of basic physics. The greater the mass, the greater the hold that mass exerts. The more things we own – the greater their total mass – the more they grip us, setting us in orbit around them. Finally, like a black hole, they suck us in… We think we own our possessions, but too often they own us.. .Every item we buy is one more thing to think about, talk about, clean, repair, rearrange, fret over, and replace when it goes bad.
