Researchers have come up with a more accurate way to calculate your dog's age

The age-old wisdom holds that a dog ages seven years for every single human year. Well, it turns out the age-old wisdom has some catching up to do. That's because scientists are now claiming that the way dogs actually age is more complex than we humans have previously thought.

Researchers at the University of California now claim that dogs rapidly age in their first two years of existence, quickly evolving from puppies to the equivalent of human middle age. They then experience a rapid slowing of the aging process in their DNA until much later in life.

It would be the equivalent of going from our mid-teens to age 40 almost overnight and then staying there for the next 35 or so years of our lives before our DNA began to rapidly deteriorate as our body prepared for death. From the Smithsonian:

"According to the formula, a 2-year-old dog is the equivalent of a 42-year-old human, but things slow down after that. A 5-year-old dog is the equivalent of a 56.75 year old human, and a 10-year-old dog is the equivalent of 67.8-year-old person."

It turns out the old 7 dogs years to 1 human year calculation was debunked by scientists several years ago. In fact, no one really knows where it originates from. They just know there's no real science behind it.

However, in some ways, the old seven-year-measurement isn't that far off, according to the new research. That's because of the DNA of the labradors in the study showed the equivalent of a 68-year-old's DNA by the time they were 10. So, in some ways, the folksy wisdom that's held true for ages is pretty much aligned with cutting edge research.

From the Smithsonian: "[T]he comparison breaks down after early puppyhood. The dog clock ticks much faster with pups speeding through puberty and reaching sexual maturity within their first year. Then, the dog's epigenetic clock slows down as the dog ages, and begins to match up with humans again in its later years. Overall, the average 12-year lifespan of a Labrador lined up with the average worldwide lifespan of humans, which is about 70 years."

If you really want to figure out how old your beloved dog is, the Smithsonian has incorporated the University of California research into a calculator. Although veterinarians and other scientists point out that dog breeds, sizes and general health factors all have a significant impact on dog's life span.

But there's good news there, too. The University of California study is far from the only project looking into dog aging and health. A major project led by the University of Washington called the "Dog Aging Project" is looking not only into dog health issues but how to eventually increase a dog's overall lifespan. Because most of us can agree that the only correct answer to the question "how long will my dog live?" is "Forever."

Hollywood is finally moving closer to equality. The past few years have seen a growing number of films starring, written by and directed by women. There's still a lot of progress yet to be made, of course. But there's one area where women have been kicking butt and taking names for decades: action films. Ironically, action films are stereotyped as the launching pad of the manliest of manly men: Schwarzenegger, The Rock, Clint Eastwood, Sylvester Stallone and so on. But some of the biggest action hits, both critically and commercially, are led by women.

If you're looking to expand your home video library for the holidays or just searching for a great holiday playlist while taking out some healthy aggression, here are 12 of our all-time favorite films featuring strong women front and center.

One in five pregnancies end in miscarriage. It's a sad and heartbreaking experience, but there still is a lot to learn from going through something so tragic. Beyoncé recently shared what she learned from her miscarriages in an "ask me anything" published in the January 2020 issue of Elle Magazine.

A fan asked Beyoncé if she was disappointed she didn't win awards for Lemonade and Homecoming. Beyoncé said her miscarriages helped put it in perspective. "I began to search for deeper meaning when life began to teach me lessons I didn't know I needed. Success looks different to me now. I learned that all pain and loss is in fact a gift," she said in Elle Magazine.

Even though 68% of women in America where size 14 or above, plus sized women tend to draw more heat for the outfits that they wear, especially if those outfits are even remotely racy. Earlier this week, Lizzo was spotted at a LA Lakers game wearing the dress heard round the internet. Dubbed the "thong dress," Lizzo's t-shirt dress was straightforward in the front, but the back featured cutouts featuring her thong and fishnet stockings.

During the game, Lizzo twerked when the Laker Girls danced to her song "Juice," giving the crowd a full view of her ensemble.

The Miss America pageant was started in 1921, but women of color were barred from participating until 1940. It took another 30 years for the first black woman to participate in the pageant in 1970. In 1983, Vanessa Williams became the first black woman to win Miss America. Now, the winners of all four major beauty pageants are all black women.

Zozibini Tunzi of South Africa was crowned Miss Universe, making this the first time in history that Miss America, Miss USA, Miss Teen USA, and Miss Universe are all black women. Tunzi is the first black woman to win Miss Universe since 2011, when Leila Lopes took home the crown.
