Your Feet Can Grow as You Age
After years of wear and tear, tendons and ligaments in your feet may weaken. This can cause arches to flatten, which means feet get wider and longer. It won’t happen to everyone, though-people who are overweight, who get swollen feet or ankles, or who have certain medical conditions, like diabetes, are more prone. If it does happen, the average gain is about one shoe size by age 70 or 80.
Holding Your Breath Can Help Stop Hiccups
It’s thought that if you build up in your body (by not exhaling), it will help stop your diaphragm from spasming, which is what causes the hiccups. When your diaphragm contracts involuntarily, it forces a quick intake of breath that’s suddenly stopped by the epiglottis-a flap of cartilage located in the throat behind the tongue. That closure is what causes the hiccup sound.
Your Teeth Shift with Age
Even if You Had Braces as a Teen Every smile is different, but a lot of this has to do with loss of the bone behind the gums that occurs with aging. If you lose enough bone-which can be exacerbated by such factors as smoking or gum disease-your teeth can shift.
Compression strength
In terms of compression strength, the femur bone of a person weighing 83kg with US size 11 feet could withstand the weight of 16,000 people standing on it at one time.
Heart beats
Your heart beats 100,000 times per day, pumping 5.5 litres per minute, which adds up to about 3 million litres of blood a year.
Nerves
There are a trillion nerves powering your memory. Studies have shown that after viewing 2,500 images for only 3 seconds, participants could recall if they had seen the images with 92 per cent accuracy.
Inner lens
Cells in the inner lens of the eye, muscle cells of the heart, and the neurons of the cerebral cortex are the only cells that will be with you your entire life.
Everything changes as you get older - your mind, your body, the way you view the world.
