Life without sugar is interestingly different. You find that sugar does indirectly make you sleepy, and that sugar in the diet begets sugar in the diet.
The ping-pong has changed a lot at school. Another former teacher has been welcomed back to the fold, and he was very good at ping-pong. It took him two days to get his form back. The day before he really got back into it I thrashed him 5-1. Then things changed as he dismantled everyone else, camping at one end of the ping-pong table. Getting him into a doubles match and pairing him with a weaker partner was the best way to supplant him. I played him on Friday afternoon and managed to valiantly lose 3-6, with many defeats that had me struggling to get passed 10 (in first to 21 matches).
