All Helium Diet

We are made out of some of the lightest stuff, like all these other heavy particles. They don't last for very long and they fall apart really quickly. And so in the same way for particles, we want to understand what are those other heavier particles, and what can they do? What be were made out of helium and we all float around, right? Tandinfla, or i guess if everything else was made of of hydrogen, we'd just fall to the bottom.
