Why select the left? the left hand although starting from the left isnt exactly the right. both hands could potentially be nice, but when left is an option, don’t take it.
About 10 percent of the population is left-handed. The rest are right-handed, and there are also about 1 percent who are ambidextrous, which means they have no dominant hand.
Not only are lefties outnumbered about 9 to 1 by righties, there are health risks that appear to be greater for left handers, too.
A 2007 studyTrusted Source published in the British Journal of Cancer examined hand preference and cancer risk. The study suggested that women with a dominant left hand have a higher risk of being diagnosed with breast cancer than women with a dominant right hand.
The risk difference is more pronounced for women who have experienced menopause.
However, researchers noted the study only looked at a very small population of women, and there may have been other variables that affected the results. The study concluded further investigation is needed.
A 2011 study from the American College of Chest Physicians suggested that left handers have significantly higher chances of developing periodic limb movement disorder (PLMD).
This disorder is characterized by involuntary, repetitive limb movements that happen while you sleep, resulting in disrupted sleep cycles.
The only 100% certain way to avoid pregnancy is to not have penis-in-vagina sex, or do any sexual stuff where sperm can get on a vulva or in a vagina (this is called abstinence).
But if you’re going to have vaginal sex, the best way to prevent pregnancy is to use a very effective birth control method (like the IUD or implant) plus a condom.
Some types of birth control work better than others. The kinds of birth control that work the best to prevent pregnancy are the implant and IUDs — they’re also the most convenient to use, and the most foolproof.
Other birth control methods, like the pill, ring, patch, and shot, are also really good at preventing pregnancy if you use them perfectly. But people aren’t perfect, and these methods are easier to mess up than implants and IUDs.
It’s super important to make sure you use your birth control the right way. This means you can’t forget to take your pill, change your ring, or get your shot on time — or you’ll be at risk for pregnancy. So the best method of birth control for you is the one you’ll always use correctly. Explore different birth control methods to find out which methods might be best for you.
No matter what method you choose, you can get extra pregnancy prevention power by using birth control and a condom together.
