Like yummymummy I had a lot of back pain and the physiotherapist basically told me I had to start exercising or I wouldn't be able to sit up long enough to do my exams (year 10 at the time). So I got my ass to the gym and started doing pilates and a class called light pace which was aimed at over 50s
Now I've aced my year 12 and am almost through the first year of uni
I am at least 20kg lighter than when the physio told me off and I'm heaps fitter. I hardly ever get pain any more
Puffer - what you said about people being nicer to you when you're thin, it's so true. It's not just in daily life either, it can be with important stuff like your career even. Before I started uni I wanted some extra money so I got a job as a barmaid. I never would have got that job if I'd been overweight. My boss noticed me eating twisties one time (quiet night) and said "nobody likes a fat barmaid you know". I'd been working 7 hours already and hadn't eaten anything... I guess it's because I usually didn't eat while I was working there but that got hard if I worked more than 10 hours my energy got really low
But my point was that if I was overweight he never would have hired me and I'm sure lots of employers are like that.
That's my rant for the day.
