Personally I believe one should only bet on horses with discretionary money that one is prepared to lose. That if lost, it will not affect one's lifestyle. That does not seem to be your situation, judging by what you just posted.

Once people start betting with money they cannot afford to lose all sorts of bad discipline comes in like betting up big to recover all the day's losses because a horse has been plunged so you don't want to miss out.

Also the simple method of selecting horses, unless purely computer generated, could be influenced because of the financial situation behind the betting. Will you be selecting the same horses if you know you are going to bet on them and "would sink for good" if things went wrong?

I'll have very substantial amounts running for me in the stockmarket on just one company if I have thoroughly researched it, like market conditions etc. etc.

But there is no way I will have a large amount running on one horse, no matter how confident I feel.

Hope this is something to seriously think about,

Cheers,
Neil.
