Now what I thought originally was another word for "change" as a username. Because I want to change some things, and I didn't want to have a username called "change" so I came up with Catalyst via a thesaurus.

Now what the topic really is, I would call the human body a catalyst really. But more in the sense of if you take medication for something. For instance, I'm epileptic (seizures), and I take medication for that. BUT, you still have seizures, but the medication reduces (well hopefully anyways) them from happening. But you're not actually "changing" the human body. What are your thoughts?

I know if you were to go to a biologist and mention this they'd be like "What the hell?", but again, what do you guys think?
