If one goes and looks at articles over the past two or so years, you will find that such a death is totally normal. It’s common for active and healthy athletes to die of a sudden heart attack during their middle-aged years. A simple internet search will reveal hundreds of stories showing the same. I suspect all that exercise, especially in our current times of global boiling, may be the culprit.
Public health officials and our society at large need to encourage people such as this to slow down and become more sedentary. At the age of 31, it is way past time this person took a more casual approach to life and let the youngsters of age 8 or 9 take over the more strenuous activities.
