Scientists have figured out how foot and brain size affects longevity
Many factors affect life expectancy. Of course, proper nutrition, adequate physical activity and the absence of bad habits help to achieve longevity. However, there are also not so obvious aspects.
Swedish scientists have found that the size of a foot can affect how long a person will live.

Lack is dangerous, excess - too.
How leg size and duration are related life?
Scientists from Sweden analyzed the life expectancy of 800 men and women from all over the country. It turned out that there is a pattern between the age of death and the size of the foot.
For example, on average, women with a size of 40-41 lived to 66-70 years. And men who died at the age of 67-69 had a 46-48 foot size. If you look at the ratio table, you can see that life expectancy is longer for people with an average foot size (size 42-43 for men and 36-37 for women).
Does foot size really affect longevity?
Nevertheless, scientists noted that one cannot rely solely on the results of the study. While there is some regularity, other factors that affect life expectancy cannot be neglected.
Researchers argue that the work could be considered absolutely correct if all the people mentioned in the research led a healthy lifestyle and did not have any diseases.
Scientists have found that physical activity can improve genetics
Here's how and how much you need to exercise.
What else does life expectancy depend on?
Many studies on longevity are published every year.
For example, scientists from Spain in 2015 found that women live longer than men due to hormones ... The female hormone estrogen increases the activity of genes responsible for longevity. It also helps eliminate cholesterol from the body, which reduces the risk of cardiovascular disease. While the male hormone testosterone tends to push men into various risky activities - fighting, driving at high speed, extreme sports, etc.
Dutch neuroscientist Dick Svaab found that metabolism and brain size also affect life expectancy. He writes about the results of his research in the book We Are Our Brain: from the uterus to Alzheimer's. The more active the brain, the larger its size and, according to the scientist, the life span. In addition, brain stimulation helpst avoid Alzheimer's disease.

Scientists have found out that Russians' favorite porridge helps produce longevity protein.
Although life expectancy is influenced by various factors, you should not rely entirely on hormones or leg size. In any case, you should not forget about an active lifestyle and proper nutrition - they certainly will help to maintain a youthful body and good spirits longer.
