Menopause? You have men to blame for that!

A new study from McMaster University has concluded that men are partially responsible for the existence of menopause in women. Menopause is very much a human phenomenon. It's very very rare in other species.

So why does it occur? The researchers think that men have preferred younger women throughout history. This is called 'preferential mating.' According to this theory, women will put all their procreation resources when they're younger. When those are spent, menopause happens.

Other researchers, however, think it's the complete opposite: Men developed a preference for younger females because older ones went through menopause. Either way, it seems like men have a lot to do with that pesky female problem.

A milk protein is used in the manufacturing of latex, which means most condoms are unsuitable for use by vegans!

Many people are concerned about condom materials because they have an allergy to latex. Considering that most condoms are made from latex, this concern makes sense. However, it turns out that those afflicted with latex allergies are not the only ones that should be questioning just what condoms are made of.

It turns out that some condoms are made with milk proteins, making them unsuitable for vegans. Vegans, unlike vegetarians, abstain from consuming not only meat but all animal products, including milk.

Many condom companies manufacture their condoms using casein, a milk protein. They may also use milk powder. Thankfully for those vegans who don’t want to give up their birth control, there are vegan-approved condoms. Glyde Condoms, Sir Richard’s Condoms, RFSU Condoms, Condomi Condoms and a number of others have all been confirmed by the Vegan Society to contain no animal products.

Sadism and masochism were named after their first practitioners!

If you've ever wondered where these words came from, well, there were two real people knowns as Donatien Alphonse Francois, Marquis de Sade and Leopold von Sacher-Masoch. Their sexual conduct so shocked the world that they got their own name.

Sade was well known for his libertine sexuality. He was accused of a number of sexual crimes like imprisoning a prostitute and poisoning another one. He would even write erotic works describing his practices.

Leopold von Sacher-Masoch was a writer renowned for his romantic stories of Galician life. He had a thing for dominating women in furs. In fact, he entered a contract with a women to become her slave for 6 months, with the stipulation that she wear furs as often as possible, especially when she was in a cruel mood.

Women are the only primates who have enlarged breasts all the time!

For most of the primate species, plump breasts last only as long as breastfeeding does – except in humans. Scientists think this is an evolutionary trick for getting men to be with them and show ability to feed children.

Scientists have developed a theory they call the 'handicap principle' to explain why women's breasts remain large at all times. According to this theory, heavy breasts honestly announce a woman's genetic health, but at a cost of carrying them around. Think a male peacock's burdensome ornaments say the scientists.
