Can people grow horns?

No, but they can grow Horny.

No.\n\nCarry a hedgehog as well. That ought to do it.

yes you can use that method, however, you can't if you don't have a red rose already.  You must take a tissue (perferably the auxillary node) of a red rose plant and harvest that to grow the new red rose.

It is highly unlikely because the epiphyses of long bones have fused by this age so as not to allow further growth. But there are little exceptions...mystery....I don't know...individuals are unique and so are their bodies. /PEACE

I think that this is a theoretical possibility, however, it is probably not something very possible with our current knowledge.   I think that because it is biologically possible to have certain traits such as excellent hearing, acute vision, agility etc... then it would be possible to genetically alter a person to have these traits.  It is unlikely that this could simply be accomplished by inserting one single gene from an animal to person.  It would probably take a full complement of genes, a ridiculous amount of immoral human embryological experiments, and a large amount of time and money to end up with a human that has superb hearing or can jump 20 feet in the air.   Treating people with certain gene products like growth hormones enhance our human physiology to produce "better" traits, but the effect of this are limited. \nSome researchers have experimented with introducing parts of one gene from one animal to another to try to induce a signifcant trait change, however this has not resulted in significant changes in morphology or development.

Each person has a  different limit to how long his or her hair can grow, but don't reach it since it is generally socially unacceptable. Most people can't grow hair much past their tushes...

I believe they produce it themselves.  Must creatures produce wax through glands (Ear wax actually is a wax).

Yes.  Rub it, or put it in someone's mouth.  It'll get bigger.

horns must not be a symbol of evil, because the ram's horn (called a shofar) is blown on one of the holiest days of the Jewish year, and it is certainly not considered evil in that context.\n\nBut I think the issue here is that you would most likely freak people out if you went about with corral horns on your head.  I don't think God would really be all too thrilled about you freaking others out!

Seriously, this will work.\n\nOnce each morning, place your head into the toilet and flush.  The negative pressure will "pull" on the budding hair folicles and will stimulate growth.  Remember to hold your breath while you do this.  You can do it again in the evening, but not more often than that.  More often, and the moisture will damage the new hair.\n\nIf you live on a farm, you can also increase the growth by rubbing dry cattle manure on your face.  Humans originally evolved hair on the face to keep dirt off of the skin, making for a more sanitary facial area for early man.  Rubbing manure on the face kicks in those prehistoric genes, and causes hair to grow.  Again, don't do this too often.  Once a day is fine.  Perhaps if you do this before you flush your face, it would be more convenient.\n\nThe combined method has worked on every single male that has ever tried it, and quite a few females as well.\n\nBoth of these methods stimulate very basic human genetic response.  So you might have to do this for a few years.  Assuming your pre-teen or early teen (and male), this will mean these methods will be growing hair when you're around 16, 18 tops.\n\nBuy that razor now.  You'll be needing it.  Please, let me know how it goes.  If you grow too much hair, I'll let you know some tried and true methods for removal as well.

You can't. It will only grow longer, not thicker. It all depends on your heredity.

No, shaving doesn't make more hair grow.  It only cuts off the tapered end leaving the blunt end at the tip.  This can make the individual hairs look thicker, but it's only an illusion.  The amount of facial hair a person has is due to hormones and genetics.  Facial hair, like any other hair on the body, also has cowlicks (swirl patterns in how they erupt from the skin).  This sometimes makes a beard look uneven or patchy.

Hell ya!!!!!!!!!!!\n  Hook em horns

You want to increase your body hair?

It means the person has a natural ability to grow plants.

Nope. It's a myth. In fact, regular exercise during one's growing years actually promotes the production of growth hormones. Height is predominantly decided by your genes. Pullups are the best bet to do what little you can to increase your height. Or if thats too difficult, simply hang from a bar.

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.
