Rose Macaulay said this quote

We may say that all ages are dangerous to all people, in this dangerous life we live. But the thirties are a specially dangerous time for women. They have outlived the shyness and restraints of girlhood, and not attained to the caution and discretion of middle age. They are reckless, and consciously or unconsciously on the lookout for adventure. They see ahead of them the end of youth, and that quickens their pace.
