Take a break, Have some negative ions to calm you.

Yoz,

Dun be too stressed mugging. Take a break.

I was searching for Rb that one of you is asking about when I chanced upon this.

There must be quite a lot of anions out there during our lessons rite?

Actually, have you ever come across some devices (e.g. aircon) that are said to be 'healthier' cos of some negative ions thingy? Here's an article which you might want to read: What's In A Breath of Fresh Air?

Ok, enough of rest, go back to your mugging.
