What parts of the human body never stop growing?

The ears, nose and feet.  Look at a photo of your grandfather when he was in his teens or so.  Now compare the size of his ears to their size now.  Other parts like nail and hair obviously never stop growing.

The total relative length of all the viens put together in a human body is between 60,000 -100,000 miles.

Dead stuff doesn't grow. Instead, what is perceived as "growth" is acually the surrounding tissues receding, or shrinking, as a result of moisture loss from the once living surrounding tissue. Hair and nails are mostly protein (keratin) and contain very little moisture (in comparison to skin cells) and thus don't shrink.

No because once what is known as the epiphyseal plate, or growth plate in your long bones have closed with solid bone which usually occurs by the early 20's, it is impossible to grow any taller after this point.

It does vary from person to person. Some people don't stop growing till quite late, but generally 19/20 is the age when growth stops.

Your penis grows as your body matures.  During puberty, men experience the largest gains in body size as they become men.  The penis can continue to grow until late teens as it is one of the last areas of the male body to completely develop.  All men are different and mature at different rates.

Females usually stop growing earlier than boys. Females reach their growth maturity (stop growing) around the ages of 18-20. Males on the other hand tend to stop growing in their early 20's (20-24). However, some people mature quicker than others, and some are 'late bloomers'. In general when puberty stops, we stop growing. \n\nhttp://www.teenadviceonline.org/archive/41056.html

There is no exact science as to when humans stop growing. The age ranges you mentioned are the general concensus. Sorry that there is nothing more definite.\nhttp://www.thedoctorslounge.net/orthopedics/forums/viewtopic.php?t=2958\n\nUltimately, we stop growing because we are genetically programmed to do so. It is our genes, made of DNA, that determine how we grow and develop. We inherit our genes from our parents when we are conceived, and we maintain this genetic blueprint throughout life. But although our genes control the growing process, scientists still do not understand just how they do it.\n \nOUR GENES start working at the moment of conception when a single cell becomes a complex organism in which billions of cells work in concert. Once we are born, we continue to grow and develop until the completion of puberty. At this point our genetic program tells us to stop growing. \n\nFrom an evolutionary viewpoint, once our genes have orchestrated the growth and development of the body to the point that it can reproduce, the purpose for growth is complete. \n\n\nWhen we think of a growing child, we often picture one who is becoming taller, whose arms, legs and spine are growing longer and whose hands and feet are growing bigger. This is referred to as linear growth. Knowing that our genetic makeup is ultimately responsible for stature, it is interesting to look at the mechanisms that stimulate and inhibit this type of growth. \n\nThe complex interplay of genes, nutrients and hormones cause bone cells to proliferate at the growth plate of long bones. This interplay is also responsible for the cessation of linear growth and the correlating inability of these cells to further multiply and lengthen bone. The key hormones in this process are: growth hormone, thyroxin, androgens and estrogen. They are secreted by the pituitary, thyroid and reproductive glands respectively.\n\nAt the completion of puberty, the reproductive glands in both males and females increase the production of the hormone estrogen. It is the high concentration of estrogen in the blood that 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. \n\nDisorders of the endocrine system can lead to abnormal growth in children and adults. Gigantism, a condition in which a person’s arms and legs grow especially long and height can exceed 8 feet, is caused by the overproduction of growth hormone when the growth plates of long bones are open during childhood or adolescence. Acromegaly is a chronic disease marked by the overgrowth of the hands, feet and jaw. This occurs in adulthood, after the growth centers of the long bones have closed. Both of these disorders are usually caused by pituitary tumors. In gigantism, the tumor develops in childhood and in acromegaly, the tumor develops afterwards.\n\nThe mechanisms by which organs grow in size are less well understood. \n\n“In fact,” says Dr. Scott A. Rivkees, an associate professor of pediatric endocrinology at Yale School of Medicine in New Haven, Conn., “we are just starting to understand the growth-promoting and growth-inhibiting factors of organs. We do know that certain organs have cells that can continue to divide once the organ has reached mature size.” Examples of organs with this capacity are the kidney, liver and intestinal lining. But the lungs and brain do not have this capacity, he says, for reasons that are not completely understood. \nhttp://msnbc.msn.com/id/3076703

The average age for growth to stop is 18, however it is not uncommon to grow after that.

It is a myth that hair keeps growing after we die. As our bodies begin to decompose after death we loose moisture and skin begins to shrink but hair and nails do not shrink therefore making it appear to be growing.

Ear cartilage and the ear in general continues to grow throughout your lifetime, however the lobe itself will only stretch as a consequence of gravity.

The growth of human hair\n\nEach human head carries roughly 100,000 hair follicles. \nEach follicle can grow many hairs over a lifetime: on average, each grows a new hair around twenty times. \nNot all these follicles are actively growing hairs at any one time. From the moment when it is first formed, each follicle undergoes repeated cycles of active growth and rest. The length of the cycle varies with the individual, and also with the part of the body on which the hair is growing. \nThe hairs on an adult scalp do not grow in unison, as they do in an unborn baby. They are 'out of cycle' with each other. If this were not so, everyone would go temporarily bald from time to time. \nThe growing and shedding of hair as a whole seems to happen at random, but for each hair follicle the process is precisely controlled. No one knows for certain, however, exactly how the body controls these cycles. \nPlucking a hair from a follicle brings forward the next period of hair growth in that follicle\nOver the years, the number of follicles capable of growing hair declines naturally. The decline is especially noticeable on the top of the head. Some follicles increasingly produce only fine, short non-pigmented hairs that look more like vellus hairs than terminal hairs. In older women, this leads to a general thinning of hair. In men it tends to lead to common baldness. If you look at a bald scalp you will see these fine, poorly pigmented hairs.

Many people believe that a person's hair, fingernails and toenails continue to grow after death. Despite what you may have read or seen in the movies, this is false. Once a person has died all growth of the hair and nails ceases. After death the body dehydrates and the skin around the hair and nails will recede a little making it appear as the deceased's nails and hair have grown. However, it is only an optical illusion. The nails and hair remains the same length as before but more of it is exposed due to tissue shrinkage.

Doctors say you stop growing at 21, but this isn't true for all people (I stopped at 13)

No growing medicines,\n\nMake sure you have correct posture.  Correct posture can give the appearance of a taller person. In some cases, if you slouch, you can add an inch or two by standing straight.\n\nCorrect posture will also prevent you from losing hieght as you age.
