Are We Rinsing With Mouthwash Long Enough?

Commercial mouthwashes are used for various purposes including getting rid of bad breath, plaque, gingivitis, etc. The American Dental Association provides a very detailed write-up on mouthwash. You may be able to get a similar benefit from a saltwater and hydrogen peroxide solutions. Many dentists state that you only need to brush and floss to support a healthy mouth.

What I have always wondered though is, assuming there is some benefit from using mouthwash, am I getting any benefit from them? The reason I question this is because the recommended rinse duration on most mouthwashes range from 30 seconds to one minute. I think I rinse for maybe 20 seconds at best. Do you rinse for one minute?

There are tons of mouthwashes out there so it can be a challenge to pick the right one for you. I found the following information for various brands of mouthwash:

Based on the above, you may not be getting the full effectiveness of the mouthwash you are using if you are not rinsing for the prescribed about of time. I guess we have to tough it out folks and increase our mouthwash rinsing time . Good luck with that!

Sapiosexual is a New Dating Term. Is it a Real Thing?

I was reading a profile of someone and they said they were sapiosexual. I thought, “Say what”? I wondered, is that being attracted to sappy people? My curiosity was piqued so I had to look up the word. From the Collins Dictionary the definition of sapiosexual is: “One who finds intelligence the most sexually attractive feature; behavior of becoming attracted to or aroused by intelligence and its use. Sapiosexual is a neologism word (recently constructed word) that has come into common usage; especially on social networking sites where some people are self-identifying as sapiosexual. Origins: From Latin root sapien, wise or intelligent, and Latin sexualis, relating to the sexes”.

Now I am thinking, great, there is hope for me after all! I like to think of myself as intelligent. I have a master’s degree, I read books; I can walk and chew gum at the same time. I’m in like Flynn!

Sapiosexual is a relatively new term being used. Dating sites such as OkCupid have even added it as a new gender and sexuality option. But is sapiosexual a real thing? There have always been people who have been attracted to intelligent people. Sapiosexual is really not a sexual orientation term. For example, being sapiosexual doesn’t mean you would be attracted to intelligent people of all sexes. If you are heterosexual, bisexual, or whatever; you would still be those things if you were sapiosexual.

My take on this is that a sapiosexual values intelligence so much that almost nothing else matters, whereas non-sapiosexuals may value intelligence but they value other things also (looks, humor, body shape, etc.). In the real world there are probably different levels of sapiosexual. That is, at the top of the sapiosexual pyramid, intelligence is the only thing that matters and at the minimum level are sapiosexuals who value intelligence at a defined minimum threshold:


In the above chart the different regions are defined as follows:

  • In region A people are more attracted to “other things” than they are to intelligence and thus, they are not sapiosexual
  • In region B people are more attracted to intelligence than they are to other things but they may or may not be sapiosexual
  • In region C people are more attracted to intelligence than they are to other things as in region B. The difference is than in region C the draw to intelligence is above a predefined level (in our case we are assuming this level is 60%). Therefore if you are in region C you are a sapiosexual.

It would be interesting to design a questionnaire to determine what the minimum threshold would need to be for people to be considered sapiosexual. What do you think that percentage is? Are you a sapiosexual? Let me know in the comments section!

Understanding African American European Ancestry

It has been a common assumption within the African American community that European male slave-owners had sex with African female slaves during the American slavery period. This period started around 1619 when Africans were brought to Jamestown, Virginia to help with tobacco crops; and ended officially with the passage of the Thirteenth Amendment in 1865 (

In one article, USA Today estimated that “About 30% of black Americans who take DNA tests prove to be descended from Europeans on their father’s side (USA Today 2/2/06, pg. 4A).

How can we confirm the above assumption? The answer is DNA. More specifically, DNA Haplogroups. Haplogroups can tell you where a line of your ancestors originated from thousands of years ago. There are two types of Haplogroups: Y-chromosome (Y-DNA) haplogroups and mitochondrial DNA haplogroups. “Y-DNA is passed solely along the patrilineal line, from father to son, while mtDNA is passed down the matrilineal line, from mother to offspring of both sexes. Neither recombines, and thus Y-DNA and mtDNA change only by chance mutation at each generation with no intermixture between parents’ genetic material” (Wikipedia).

Since only males have Y-chromosomes, women can’t trace their ancient paternal ancestors. They have to have one of their male relatives do it. Conversely, even though mothers pass their mtDNA to both their male and female offspring, only females can pass their mother’s mtDNA to their own children. So males may have to have one of their female relatives trace their ancient maternal ancestors. Continue Reading!
