Det ges tydligen utbildning numera i hur man raggar. Någon sådan verkar inte John Maynard Keynes, en av 1900-talets mest framstående nationalekonomer, ha behövt. Han var, åtminstone i sin ungdom, uppenbarligen framgångsrik på den s.k. köttmarknaden, vilket han dokumenterade i två dagböcker:
In earlier days, though, from 1901 to 1915 when he was mostly a 20-something, he cruised constantly and kept two sex diaries of his success. … Keynes obsessively counted and tabulated almost everything; it was a life-long habit. As a child, he counted the number of front steps of every house on his street. Later he kept a running record (not surprisingly) of his expenses and his golf scores. He also counted and tabulated his sex life. .. The first diary is easy: Keynes lists his sexual partners, either by their initials (GLS for Lytton Strachey, DG for Duncan Grant) or their nicknames (‘Tressider,’ for J. T. Sheppard, the King’s College Provost). … You might say that Keynes was at least as invested in the sex market as the stock market.
