I know several people that have died or almost died from Widowmaker heart attacks. Seeing a cardiologist and cardio in general is one of those things that a lot of men ignore because they feel healthy but it cannot be stressed enough, once you hit 30/40s, find a good cardiologist especially if you have a history of heart attacks in your family.
I will never forget seeing a family member with their sternum cracked wide-open heart bypass, where they connect your heart to a machine while you are suspended in animation, so they can operate on bypassing your clogged arteries that could have been managed with a healthy lifestyle and drugs.
