So what does every man think apart from sex? Apparently nothing, claims British author who has written a book on it.
Quite fittingly, the book has just a cover and 200 blank pages inside.
Sheridan Simove's What Every Man Thinks About Apart From Sex has become a surprise bestseller on Amazon.com.
The book has hit number 744 on the Amazon list, ahead of Dan Brown's The Da Vinci Code (number 2,910) and JK Rowling's Harry Potter And The Order Of The Phoenix (2,406).
It is also picking up as a novelty gift among amused uni students in the UK who are flocking to grab a copy of the $7.95 paperback .
A student from Nottingham University says she picked up the copy for her friend.
"I bought a copy for my mate as a joke and he started using it as a note pad for lectures. Now everyone seems to have one. It's started a real craze on campus".
The book’s 'author' says he never expected his work to become a bestseller.
"When the book was published I never imagined in my wildest dreams that I would outsell Harry Potter. But Britain's students seem to think my book is magic and who am I to argue?" Simove has been quoted as saying by news reports.
An Oxford University psychology graduate, 39-year-old Simove says his next research project is a PhD on the subject of what women think apart from sex.
"I hope to publish my findings in another decade," he jokes.
