Hybrid Cars. I know they’ve been a popular choice over the past several years, but it truly seems like they’re all over the place now. Hybrids are a common sight on the roadways, they’re parked in plenty of garages and driveways and the next time you’re at the mall, the local park or the grocery store take a look around you when you’re in the parking lot — they’re everywhere.

Prior to this month, I don’t think I’d stepped inside a sauna for close to two decades. Back in the late ’80s, my family made an epic drive from Newfoundland, Canada, to Middle Tennessee, and I remember us stopping at a couple of hotels up north that offered such amenities.

When you’re 7, however, you’re not really in a position to appreciate the finer qualities of a good lengthy sweat. Three minutes of squirming and pouring too much water on the stones is generally enough to satisfy your hyperactive curiosity (or get you kicked out, whichever comes first).

So the next 20 years passed by relatively sauna-free for me. After all, most of that time was spent in the American South. But a few weeks ago, the masterminds at HowStuffWorks.com assigned me a couple of articles on saunas (How Saunas Work and 5 Strangest Saunas) and all of this changed.

On Friday, I highlighted Banned Books Week, but tomorrow kicks off another week of note: National Trichotillomania Awareness Week runs October 1-7.

Trichotillomania is an impulse control disorder in which people can’t resist the urge to pull their own hair out. In some people, it’s a very mild condition — they may absentmindedly pull at their hair while they read or watch television. But for others, the need to pull out hair is overwhelming and may take up hours of their day. They may develop elaborate rituals where they search out specific hairs to pluck. So much hair pulling leaves people with patchy bald spots on their head, and eyebrows, eyelashes and body hair may also be affected. Many people chew or eat the hair once they pull it, putting them at risk for developing large hair balls that can cause gastrointestinal problems.

If you were to inseminate a female chimp with human sperm, or a female human with chimp sperm, would you end up with a humanzee – a human/chimp hybrid? Could it even work? It seems like it might work, because there are several examples in nature. A liger is a cross between a lion and [...]

I didn’t know this until this weekend. A manufacturer is able to put a DOT sticker on a motorcycle helmet because the manufacturer believes that the helmet meets DOT standards. But that does not mean that the helmet passes the actual tests. For example, here is a detailed review of the AFX FX-28 helmet: AFX [...]
