Survival of The Fittest

A study that has been running in Western Australia for 20 years called the Health in Men Study (HIMS) has shown some surprising results.  They recruited in the late 1990s and 12,000 men were screened and followed up repeatedly over the last 20 years. One of the unique features was that they recruited men over the age of 65 and now have followed a group of men well into their 80’s and 90’s.

They found that for older men, being slightly overweight but not obese, you are less likely to die That high levels of vitamin D in your bloodstream was associated with less frailty. The risk of brain impairment increased with the use of full cream milk and that mild alcohol consumption and physical activity were protective to brain function.

So we can get overweight, not wear our sunscreen, drink alcohol and we’ll live longer and healthier!  Better not quote me on that!

It seems that physical activity is protective for your physical and mental wellbeing and more important than being slightly overweight (but not obese).  Sunscreen has been protecting us from skin cancer but decreasing our Vitamin D levels and maybe increasing our risk of breaking bones. Other studies have shown that low levels of Vitamin D increases your risk if erectile dysfunction and lowers you sex hormone levels.

Low levels of testosterone were associated with higher levels of depression and worsening mental function.  The best way to improve your level of testosterone is exercise.

So guys, nothing earth shattering here.  Look after your diet, exercise, don’t get too overweight, happy plenty of mental stimulation and you’ll be happier and healthier.
