riddle me this (inspired by insomnia)

What’s got both ridges and valleys
which tell time,
Can withstand the weight of mankind
but not for long,
Can be used for love or hate
and to experience the world,
Has languages of its own
but can also be quite mindless
Can lead to one’s destruction
or to one’s survival
Can be the epitome of cleanliness
or the harbinger of disease
Can create masterpieces
or deal with mistakes,
That most everyone has?
