Maybe they have already heart problems so once they saw they win in jackpot lottery they suprised and it will the cause for them to trigger their problems in the heart. If they did not won maybe they still alive but maybe that is alsp their time. I want to know how about those winnings in jackpot those people died because of that and still not unclaimed where the money goes? I hope in their relatives or family because they lost their love ones because of that so it is really needed for them to get the money for their future.
Myself too think the same way. Most of the time cardiac arrest happens with people who are already suffering from heart disease. People who comes out of the first time cardiac arrest used to survive longer on medication. These people shouldn't get overjoyed or deep sadness. When one wins jackpot, there'll be happiness overflowing. This sudden change of state makes changes in the blood pumping and causes cardiac arrest. Another thing, it happens mostly with people who have the mind to enjoy the moment, but out of excitement they control and feel the happiness within themselves.
