I was fairly active physically. I had one of those soapbox carts, a sledge, a bicycle, roller skates, and I remember using those things. Dad used to take me swimming, and I loved that. A lot of my activity was solo stuff. I remember going round the estate with pencil and paper to make a map. I also spent quite a bit of time with other kids, roaming round with them, often as a pair, and looking for something to do. I was poor at sports but I was interested enough in them for a while. Luckily we didn't take sport very seriously in those days, it was just a bit of fun. We invented some of the games we played, and created variations of others. So we'd do stuff like running round the garden till we were tired out.
I used to play alone in a sandpit in the garden, and at one point I went out every day to work on digging a hole as deep as possible, just to see how far I could get. I took to going downstairs by climbing over the rail at the top, hanging by my hands, and dropping to the floor. Sometimes I'd forget to take my house key to school, and when I got home I'd climb up the drainpipe and get in through my upstairs bedroom window. I also enjoyed climbing up onto the flat shed roof.
But when I was about 11 years old, I became rather lethargic. I found it hard to get up in the mornings and I tended to confine myself to sedentary interests. I'd just started going to the grammar school and found the work so long and hard that I was genuinely tired out. And my social life had dried up by then, as most of the kids I knew had moved out of the area and the school was a long way from home so it wasn't really practicable to meet up with the very few friends I'd made there.
