What a load of bullshit. PD/H/PE prac is good, yeah, of course (not being sarcastic). Theory is awesome but! Who doesn't want to learn about what smoking dope and cigarettes does to your body! (Or didn't you study this in Yr 8-Yr 9?)
SO I will assume that you are one of those people who thinks it's 'cool' to smoke and inhale over 40 (or possibly FOUR HUNDRED, I forget) different TOXIC chemicals into your body. And it's 'cool' to be ignorant about the health effects of smoking and alcohol, and just kill yourself twenty years before it's due, hm?
