The living body
Last Wednesday I attended a lecture was about the integumentary system: skin and hair. For me, it was really interesting because I learn some new information about the hair. For example, average human scalp includes about 100,000 hairs, and hair growth and density will be affected by nutrition, gene and hormones. Also, on average, human will lose about 100 hairs a day; furthermore, high fever, emotional stress, and excess vitamin A can lead to temporary hair thinning. Above the information are something we never know before, but it may happen in our daily life.

Sharon,
I'm glad to know you find the York lectures interesting. There are probably lots of things we do not know about the human body.
