Lots of playing, not much jumping progress!

I went on a diet and lost about 14 pounds through exercise and eating very little. I also had been taking some medicine for a fungal toe infection. After several weeks of the diet my skin suddenly improved and became soft. I thought it might be from the medicine. I have been battling dry and itchy skin for years. Now I have stopped the diet and after a few weeks the skin condition returned. I thought my eating habits were pretty good but apparently not. I need to make it a permanent change not to eat sugary breads and donuts, eat more salad, and eat very little!
On the basketball front I played in several tournaments this year. The big 1st tournament in Lao I played for the Chinese team. Just before that tournament started I tore my right hamstring and it was black from bleeding. I hopped and hobbled through the tournament and played OK. The second Lao tournament was a nightmare for me. I could not get a shot without being fouled and the refs were not calling them. I lost my temper many times and it was the worst experience I ever had playing basketball. I didn't even show up at the last game because there was no fun in it. In Thailand I played an over-40 tournament. our team wasn't very good but it was fun! I played pretty well. the highlight was the last game when we were getting blown out and the last quarter my teammates asked me to score. And I made some good shots. And finally the 3-on-3 40+ tournament in Udon Thani. It was a star-studded event with big crowds and a DJ.

We lost the first game and I got a bad injury, a sprained thumb (no foul called) which also turned black and yellow. I was taped up for the final a week later not knowing if I could play and had my best game in a while scoring 5 shots and 4 foul shots in 10 minutes.
Now back to the subject... dunking. I bought myself a safety harness for construction workers and chained myself to an old steel cement bucket at my house... tried dragging it to build my legs but could hardly budge it. I am planning to pour a cement weight that is round and will offer less resistance on the ground. I will get a pic out when I do it.... uh finding time...
Injuries? I am pretty good right now.... just the Achilles heal on my right foot giving me some pain.. I have some calcification build up from repeatedly hurting it.
I haven't given up yet even though 52 is a few months down the road. I really would like to end my frustrations with the Lao refs and the fouling by coming out dunking next year.. otherwise no desire to play in that mess again!
