Physics, geology, art, chemistry, and not necessarily in that order. Oh, and athletics.
I was the only person in my high school to be awarded a national 5-star certificate from the Amateur Athletics Association. I remember having a conversation with the athletics teacher's 'side kick', or 'little helper' as I sometimes called him, among other more significant derogatory phrases. He asked me why am I interested in knowing what is required for the maximum 5-star award, as he said I wouldn't be able to achieve it. He said I would get a 3-star award at best. At the time I thought his response was what was to be expected, from someone who owns and drives an MG Metro.
I managed to get the 5-star award without really trying hard for it, and still without knowing what was required. I just did the best I could do, and did it without any significant training. 100m; 200m; long jump; triple jump; high jump; discus; shot put and javelin.
As for team sports, basketball and Rugby (outside centre or occasionally on the wing). I had a dislike for football (soccer). Still do, as to me it seemed to be full of prima donna's.
I remember seeing my athletics teacher's 'little helper' after I left High School. He was still driving a red MG Metro. I waved at him as I was overtaking him, along with some other hand gestures. There was no love lost.
