The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature, l regard this as the major discovery of the past hundred years of biology. It would have amazed the brightest minds of the 18th century Enlightenment(启运动) to be told by any of us how little we know and how bewildering the way ahead seems.

How hard is it to get beautiful hair
Beautiful hair cannot be taken for granted. Environmental factors, chemical treatments and the mechanical damage done by combs, brushes and blow dryers all have a bad effect on the hair in the long nm.
