I never gamble on horse racing betting for the simple reason that I don't know anything about horses. I know a bit about donkeys as I used to own one, but pure breed racehorses is not an area I am familiar with. Goodness knows how much money I would have lost if gambling on a sport I know nothing about - there are of course millions of others who also know nothing but still put on a horse racing bet often!
The Dosh for U advice here for horse race betting is simply not to bother betting at all unless you read up, study and know the true odds. It is only the select few who do this who make a decent living out of it.
