For instance. Wild worms can carry parasites and germs that can be harmful. It comes down to the soil conditions they are living in and the environment. Worms that are farm raised for eating are fed pest-free food that helps keeps them clean and parasite-free. This is why buying worms from a reputable dealer is preferable to going out and hunting your own worms.
Infinity has no end. Infinity is the idea of something that has no end. In our world we don't have anything like it. So we imagine traveling on and on, trying hard to get there, but that is not actually infinity. So don't think like that (it just hurts your brain!). Just think endless, or boundless.
Infinity does not grow. Infinity is not getting larger, it is already fully formed. Sometimes people (including me) say it goes on and on which sounds like it is growing somehow. But infinity does not do anything, it just is. Infinity is not a real number. Infinity is not a real number, it is an idea. An idea of something without an end. Infinity cannot be measured. Even these faraway galaxies can't compete with infinity. Infinity is Simple. Yes! It is actually simpler than things which do have an end.
