How important do you think being in a normal bmi is?

It isn’t the end-all-be-all. It’s a tool, just like anything else, and it does a poor job of taking body composition into account. I use a healthy BMI range as a guide for what I think my goal weight is, but I know I have a relatively large frame and I have a decent amount of muscle, so my goal is at the higher end of that healthy range. Plenty of people may be considered overweight according to their BMI while their doctors consider them to be perfectly healthy.

Quick fact. Ready?
Our lungs are actually elastic. It’s crazy, isn’t it! With every exhalation, our lungs snap back to its smaller size. Even when there is only a little bit of air being stored, they still want to get smaller.

How do they not collapse completely? There is a negative pressure surrounding the lungs that prevents this. This pressure must be kept sub atmospheric, our else the elastic walls of our lungs will give out and possibly collapse!

The human body is amazing, isn’t it.

9 Ways to help Avoid Dementia, say scientists:

A third of dementia cases could be prevented by making environmental and lifestyle changes starting in childhood, scientists have claimed.

The panel of 24 international experts identified a range of modifiable risk factors they believe to be responsible for around 35% of all instances of dementia, including Alzheimer’s.
Different risk factors were said to make an impact at different stages in life, having an accumulating effect.

Better education in early life and addressing hearing loss, high blood pressure and obesity in mid-life could reduce the incidence of dementia by up to 20%, the research suggests.
In later life, stopping smoking, treating depression, increasing physical activity, managing diabetes and enhancing social contact could reduce dementia rates a further 15%, according to the findings.
