It's World Heart Day, and I stumbled upon an article written for the occasion. They say on the Hungary it the number of heart attacks among below 40 are growing, just as world wide. They also note the high number of cardiac failures among athletes and other sportsmen. They give a number of risk factors: genetic dispositions, drugs usage, illnesses, smoking, high cholesterol, and overweight (I'm sure the 5 latter are frequent among athletes... - well perhaps drug use) - but they abstain from mentioning such silliness like corona or the vaccines.
