Yeah I was just a part-time guy when I was 17 or so but it always seemed like it just ticked along. Did well enough to open a shop in Arundel and another in Chichester at least.
Easily the best job I've ever had.
I tried it a few years ago but find I have difficulty with my knees / lower back when running. Didn't think that was possible at 33 but hey-ho.
Sticking to low impact cardio like rowing.
