I've been thinking about this for a while now, so here goes...
"Hi my name is fish, and I have a netball addiction."
There. Done. I feel better now.
What to do about it? I know my ankles are starting to show the strain - I hate to think how I will be able to walk 20 years from now. I can't even rise up on my toes on my left foot without pain. Netball keeps me fit, but I think perhaps six games a week is too much. There comes a point where "getting exercise" is outweighed by "walking cos I can't run", and you're not much use to the team. Less is more perhaps.
Thought for the day: You can only sprain a ligament a few times. The other times you sprain scar tissue.
