I might just add that I've had a recent personal experience which I found upsetting. A guy who works for me's son was in the ute that collected a tree in Upper Ferntree Gully the wet weekend a couple of weeks ago. His son is relatively OK, but 1 is dead and the other on life support and on last report. The whole incident has left him visibly affected. You can see the trauma in his eyes and face and in his voice. I won't go into details but the story is horrendous for all involved and will shape lives forever.
Don't do it to yourself, don't do it to your parents, don't do it to anyone else. It's very serious stuff, that young men little understand or care for until it is way too late.
Be careful and responsible and promote it in others.
