Dog tried to eat my skate

got bit by a dog on the skate today, and the owner barely attempted to control the dog during its grapple at my ankle.
They asked me if I was ok, I said yes and skated off in a huff. Why can't people own small dogs in the city, or at least muzzle their dog if its likely to go at people on the footpath.
Sheesh
Last night I watched Catalyst, which is a science program on the government owned channel. It had an interesting article on how dementure is caused and how by simply running regularly keeps the arteries in your brain from hardening and crushing nerve cells. They also found that new nerve cells are generated in older people who are debilitated and then take up exercise.
So, if your concerned about getting old, they recommend exercise and crosswords or puzzles, I would say things like Sudoku and stuff like that would also be really good.
I have omitted heaps of stuff said on the article, one of the key points were that if the heart isn't healthy then the brain will follow suit, so keep your heart fit and healthy and the brain thrives.
