The picture posted along with this thread looks just like my brother (it's not), who died suddenly, unexpectedly, 12 years ago, when he had just turned 62.
I say ironically, because, he never exercised, but wasn't over-weight, never smoked, nor drank alcohol excessively. And yet, after preparing a lifetime for his security and retirement, saving and investing, he was to retire, his last of work, on the Thursday, which was to be his 62nd birthday, Halloween. However, the lady in HR had recommended that he work on the Friday, which was the 1sst of the month, and that way he'd automatically be covered for the month of November on healthcare. So he did. All plans in place. Yet, on the Monday, he took a shower, followed by his wife, who a few minutes later, came out to find him slumped dead on the floor from a massive heart attack.
The actions we take in our 40s, proper nutrition, exercise, stress reduction, sleep and mental engagement, along with preventative healthcare, boost our likelihood of not just long life, but health, physically and mentally. This is in no way controversial, and yet, for the vast majority, denial not only of the inevitability of death, but likelihood of infirmity and loss of independence, and the steps which can be taken to mitigate or delay that likelihood, or impact, is ignored.
