Legalizing Prostitution Increases Health and Safety

Prostitution isn’t going away anytime soon (or ever) and as a result ought to ensure the safety of those involved in the field. In many places sex workers are abused and exploited and that’s not a good thing.

A new study from Australia found that no matter what the laws are around prostitution it will still occur; however, if it’s legalized than sex workers are healthier and safer!

Sex workers in Sydney, where adult prostitution is decriminalised and brothel locations are regulated through local planning laws, have access to the best-funded support program at $800,000 a year.

Sydney sex workers were also more likely to report regular contact with a health worker compared with those in other cities.

Sydney has about 200 brothels within 20 kilometres of the city centre, the research found, all operating legally – but many without planning permission.

Scratched Lenses for Clearer Vision

As we age our eyes start to degrade and often require glasses to correct vision issues. For many people bifocals are an imperfect solution. Some new research suggests that glasses of the future will be able to keep everything in focus at the same time by putting fine scratches on the lenses.

It involves engraving the surface of a standard lens with a grid of 25 near-circular structures each 2 millimetres across and containing two concentric rings. The engraved rings are just a few hundred micrometres wide and a micrometre deep. “The exact number and size of the sets will change from one lens to another,” depending on its size and shape, says Zalevsky.

The rings shift the phase of the light waves passing through the lens, leading to patterns of both constructive and destructive interference. Using a computer model to calculate how changes in the diameter and position of the rings alter the pattern, Zalevsky came up with a design that creates a channel of constructive interference perpendicular to the lens through each of the 25 structures. Within these channels, light from both near and distant objects is in perfect focus.

Avoid Fat Kids by Owning a Dog

Recently Canada has been identified as being filled with fat people, and there’s a simple way to stop this waist problem from expanding: own a dog. Families that have a dog have kids who are fit and thinner than non-dog owning families.

Go play fetch and stay fit!

And an Australian analysis of 1,145 children found girls and boys with dogs 50 per cent less likely to be fat.

“If you’re a kid and a dog, you chase balls, you play soccer with them, you rumble with them, wrestle them on the carpet even if you’re watching TV,” said Jo Salmon of Deakin University in Victoria, Australia. “It’s activity and it’s a mind thing as well.”

Children whose families owned dogs were more active, with increased light, moderate and vigorous physical activity, regardless of race or gender, reported Christopher Owen, an epidemiologist at St. George’s, University of London, who led the English study.

“The more active lifestyle of children from dog-owning families is really interesting,” he said. “Is it that owning a dog makes you more active or active families choose to have a dog? It’s a bit of a children and egg question.”

Keep Learning for a Good Life

For some reasons that I don;t understand people find learning to be dull. If you’re one of those people this post is for you!

Learning is a great way to keep your mind active and acquire new skills to improve your life and ways you don’t necessarily foresee. There’s always areas that you can expand your knowledge in and lucky for us someone has put these into a handy blog post.

Here’s a snippet:

Challenge Yourself
Finally, give yourself a challenge or two. Next time you say, “I can’t”, stop and think. Maybe you really can’t cook … yet. There’s nothing stopping you learning.
Sure, you might find that you just don’t enjoy cooking. But at least you’ll know that you could put together a meal if you had to.
We start at a zero skill level for everything in life. Just because you can’t currently play the piano doesn’t mean that you’ll never be able to. With the internet, there’s a huge amount of content on every topic you can think of – and loads of it will be aimed at beginners.

Packing Healthy Lunches

The CBC has put online a question and answers interview with some dieticians about how to pack a healthy lunch for kids at school.

There is no reason why you can’t pack a healthy lunch for yourself too!

What are common misconceptions?

Cohen: A lot of people think healthy lunches taste boring, that it’s rabbit food or that it tastes all the same.

How can parents create healthy meals?

Cohen: What’s really important to take small steps. With any program you should not turn everything upside-down. The key is to be educated, talk to your kids and make small changes.

For example, use whole-wheat pasta, low-sugar yogurts and add more fruits to your child’s meals.

Instead of saying “healthy lunches,” talk about balanced eating with your kids. Once they start eating healthier and they go back to trying processed foods, they won’t like them as much.
