How much skin does the average person have?

On average, the human body is covered with around 20 square feet of skin, which weighs about 6 pounds.

Do identical twins have the same fingerprints?

No, even twins have different prints, though the differences are often subtle and detectable only by experts.

What causes goose-bumps?

The contraction of muscle fibers in the skin produces more heat, raising the temperature of the body. This is why your skin puckers in the cold.

How can tattoos be removed?

Skin grafting, infrared coagulation treatment, or salabrasion (table salt is scrubbed into anaesthetized skin) are options. Also, hypertonic irritant solution disperses tattoo pigment particles, but cause scars.

How much does human hair grow?

Each hair grows an average of 9 inches a year.

Does hair grow faster in summer or winter?

Human hair growth increases during the summer 10% because warm weather facilitates blood circulation, nourishing hair cells. In cold weather, blood is needed for warming internal organs and less is circulated to the skin.

How many hairs are on a human head?

An average person has about 100,000 hairs on their scalp. Redheads have 90,000 while blonds have 140,000; brunettes fall in between.

Most people shed 50-100 hairs a day.

How fast do fingernails grow?

Healthy nails grow about 0.8 inch a year. The middle fingernail grows faster because the longer the finger, the longer the nail. Fingernails grow four times faster than toenails.

Do nails and hair continue to grow after death?

No, but it looks like it sometimes because the body begins to dry out between 12 and 18 hours after death and fingertips shrink.

AUSTIN on February 02, 2008:

Its pretty weird i was checking a fact on a triva game and got stuck reading it.

Duchednier on November 08, 2007:

Your last comment is wrong actually. Hair, skin cells, toenails all live and grow after death. Not long of course, but at least a day or 2, because there is still oxodized blood in the veins at the time, and the cells can still live off that, and then once the blood is drained of its oxygen, there is still glucose inside the cells themselves, then after that they all slowly die, but its not until then that they stop growing.

Lisakg from Caribbean on November 08, 2007:

This is so interesting. It reminds me of the verse in the bible which says God knows every single hair on your head.

Ashok Rajagopalan from Chennai on November 01, 2007:

Leis on October 13, 2007:

I don't belive that there is around 100 000 heairs on the human head......more like millions!!!!!!!!!!!! Who would actually count every single little hair?

Amanda Kendle from Perth on September 11, 2007:

I was happy to read about the hairs on a human head question - I teach English to foreigners and often use a quiz that includes this question to practice talking about big numbers. Once I had a student who had actually scientifically calculated how many hairs were on his head by taking some sample sections and counting them - he worked it out at around 100,000 too (he was a singer in a band and was worried about going bald!). Interesting facts, thanks!
