If you can't risk it, there is no point in even giving it a thought in the first place. The little you are comfortable with wagering in any bet keeps your mind at rest and at peace whateverthe result of the game comes out like. You have not much to worry about because you stake little, but you see the type of risk that those gamblers take that say, "no risk, no reward," and they take high risk and stake high. The level of unrest they have in them while they wait for a game result is something that can send a BP patient straight away to the hospital.
Gambling is all about risk getting involved is risky and staking high keeps the mind of the gambler in a high risk that is why it is not healthy to go all in with the amount you can not afford to lose in gambling, if you can use a little amount to gamble it is better since you will not be too worried to know what the outcome will be but using a big amount to stake will always keep your mind in an unrest situation because of the amount involved and if the outcome does not go as you expected if you are not careful it may lead to something bad. For someone with a sign of BP you don't need to be a gambler it will cause more harm than good to you.
