Human ears do stop growing although they appear to grow because the body shrinks as we age.

It's because of the effects of gravity and skin changes that make the ears appear to be growing when in fact they really are not growing.

The body parts that  seem to never stop growing are the earlobes, noses, and ear muscles that keep getting bigger as we age because the rest of the body shrinks.

The body part that stops growing first are the hands and feet.

After the hands and arms the arms and legs then also stop growing.

As you progress through puberty your growth plates mature and then at the end of puberty the growth plates fuse and stop growing.

A good way to know if you will still grow and have growth potential is through an X Ray of your wrist.

The X Ray of your wrist is called a pediatric bone age  and it shows if your growth places are still open or not.

If your growth plates are still open then you will likely still grow but if your growth plates are closed then you stop growing.

Your body knows to stop growing when the bones fuse together.

The high concentration of estrogen in human blood is what causes the growth plates of our bones to fuse.

This fusion effectively closes the growth centers of long bones and renders them unable to respond to the hormones that initiate growth.

Humans take so long to grow as the brain which is hungry for energy diverts energy from our bodies which slows down growth and leads to a long childhood and adolescence.

Humans are considered late bloomers and late growers when compared with the other primates.

Growth hormones are made in the pituitary gland, which is the most important factor for growth and growing fast.

Things that makes us grow fast are proper nutrition, plenty of sleep, exercise, water and growth hormones.

The 4 things that humans need to grow are food, water, air and exercise.

As humans we also need growth in every capacity: spiritually, intellectually, physically, and emotionally.

Development in all four areas is key to a healthy life.

The age that your body grows the most is between the ages of 12 to 15 years of age.

Growth spurts for boys is around 2 years later than the growth spurt of girls and by age 16 most boys have stopped growing although the boys muscles will continue to develop.

The fastest body part to grow is the skin.

As your body grows your skin also grows and stretches to fit your growing body.

The fattiest organ in the body is the human brain which is made of fat and not only does the fat make the brain the fattiest organ the fatty acids are also very crucial for your brains performance.

The organ that humans do not need is the Appendix.

Humans can easily live without an Appendix and a lot of people have the Appendix removed before it bursts and live just fine without it.

Other organs and body parts that you can live without are wisdom teeth, teeth, Coccyx, External Ear, Male Nipples, Arrector Pili, Plica Semilunaris.

The only body part that cannot repair itself is the teeth.

While new teeth can grow once baby teeth fall out the adult teeth cannot regrow or repair themselves once damaged and need dental work to repair and treat.

The only body part that grows back is the skin which can regenerate although the liver is also an organ and body part that can also grow back.

Other parts of the body that can grow back are fat, brain tissue, fingernails, toenails,

Regeneration means the regrowth of a damaged or missing organ part from the remaining tissue.

As adults, humans can regenerate some organs, such as the liver.

If part of the liver is lost by disease or injury, the liver grows back to its original size, though not its original shape.

Although some people who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant.

Researchers from Michigan State University believe blood clotting factor fibrinogen may be responsible.

While some brain tissue can sometimes regenerate the brain actually can't regenerate itself well because when the brain is damaged its cells find it harder to make new ones.

This is because the brain has very few of the special cells, or stem cells.

Humans can't regenerate body parts other than skin and tissue or nails because mammals have more complex biological structures; limb regeneration would require sophisticated controls to ensure that limbs and organs don't grow out of control.

Humans, for example, are already equipped with safety mechanisms to ensure that individual cells don't grow uncontrollably.
