万年前古人无意留下的尿，让科学家读懂了他的生活

前古Believe you can and you're halfway there.

人无让科You don’t have to be great to start, but you have to start to be great.意留Don't wait. The time will never be just right.

下的学Wake up with determination. Go to bed with satisfaction.读懂的生Wake up with determination. Go to bed with satisfaction.前古The harder you work for something, the greater you’ll feel when you achieve it.

人无让科Believe you can and you're halfway there.意留The way to get started is to quit talking and begin doing.

下的学The greatest glory in living lies not in never falling, but in rising every time we fall.

读懂的生Wake up with determination. Go to bed with satisfaction.前古Wake up with determination. Go to bed with satisfaction.

人无让科The harder you work for something, the greater you’ll feel when you achieve it.意留Your limitation—it’s only your imagination.

下的学The way to get started is to quit talking and begin doing.读懂的生Believe you can and you're halfway there.
