11 facts that could save your life!
1. Women live longer than men.
In 1800, the average human’s life expectancy at birth was 33 years of age for women and 31 years for men. Today that number has hugely increased with life expectancy for women reaching 83.5 years and for men 79.5 years. In both cases however, women live about 5% longer than male counterparts. The gap between the gender varies across the globe though, with different social, economic and cultural factors often playing key roles. In Russia for example, women are expected to outlive men by 13 years due to heavy drinking and smoking habits amongst Russian males. One biological explanation for this gap comes in the form of our genetics. Women have two X chromosomes, whereas men have an X and a Y. Having two X chromosomes means that women keep doubles of each gene so they have “backups” in case one is bad.
2. Always remember the rule of 3.
One of the greatest survival lessons to be learned is the Rule of Three. This rule is that human beings can survive three minutes without air, three days without water and three weeks without food. A few amazing people have been able to beat the odds though and survive in outstanding situations. In December of 1912, an Australian geologist by the name of Douglas Mawson set out on a mission to explore Antarctica. After one of his two colleagues fell into a crevice taking most of their sled dogs, provisions and equipment down with him, Mawson and his remaining team member were forced to eat the dogs they had left and continue their torturous trek through the harsh Antarctic conditions. Eventually, Mawson’s travelling companion died from seizures leaving Mawson to go on alone and, against all the odds, he ultimately made it back to camp alive.
3. When wet your body loses heat 20 times faster!
Brrrr. When fighting the cold, it is crucial to stay dry. Once wet, your body begins to lose heat up to 20 times quicker than when dry! If you have to get wet, you can remove your clothing and keep them dry. Wait until they are fully dry to put them back on. Although this is potentially dangerous in cold situations, it is crucial to your body’s function in hotter temperatures. When your body heats up, it releases sweat so that your body is able to cool down. During intense exercise, your body loses 85% of the heat it has accumulated through sweating. The rest is released through breathing.
4. 30% of pregnant woman get non-food cravings.
Craving non-food items is an eating disorder known as pica. This condition is predominant in pregnant women, small children and people with developmental disabilities like autism. The most common cravings in pica patients are; paper, clay, paint or drywall, chalk, soil, metal, glass or sand. This condition can be deeply damaging to the human body as items like glass and metal can cut the intestines, throat or other internal organs. Ingesting paint or drywall can also have serious consequences. The consumption of paint or drywall containing lead can lead to lead poisoning which can then lead to severe brain damage in small children most notably.
5. Hot laptops can cause infertility.
If you’re a man and your laptop starts to feel hot, DON’T put it on your lap! Studies have found that this may lead to infertility. Scientists and medical researchers have concluded that this is due to the elevated temperature of the computer leading to an elevated temperature of the scrotum. This increase in temperature lead to a 40% decrease in the sperm concentration. While we’re at it, stay away from cigarettes too. Smoking can often be linked to impotence in males.
6. Men can have positive pregnancy tests.
Don’t freak out guys, you aren’t pregnant, but you could have testicular cancer. If a man urinates on a pregnancy test and it comes out positive, it may be a sign that he has testicular cancer. Pregnancy tests are designed to detect a hormone called human chorionic gonadotropin (HCG) which appears not only in pregnant women, but also in some cases of men with testicular cancer. In November 2012, a user on social media site Reddit posted a humorous image about his male friend taking a pregnancy test and it coming out positive. Following multiple comments by other users urging him to get his friend tested, he ultimately did and the early stages of testicular cancer were detected, saving the young man’s life. However, the American Cancer Society claims this is not an effective method of diagnosis, as the hormone does not appear in every case.
7. If you have a red eye in a picture, it may be cancer.
Ever taken a picture of yourself or a group shot with flash and everybody has glowing red eyes? Annoying right? Well, that red-eye effect may just save your life…or somebody else’s. If you spot only one red-eye from the flash, and the other has remained completely normal, it may be the sign of retinoblastoma, a type of eye-cancer. No need to freak out though, adults, retinoblastoma is a very rare form of cancer and is most often found almost exclusively in young children. Most will survive this form of cancer, however, many will lose their sight or have it greatly deteriorated. In severe cases the eye has to be completely removed! So, next time you take a selfie with a flash, pay extra close attention to your eyes!
8. Symptoms of heart attack are different in women and men.
The first symptoms of a heart attack in men are mostly related to and contained in the chest area. For women, the symptoms are different. A woman having a heart attack will experience; neck, jaw, shoulder, upper back or abdominal discomfort; difficulty breathing; right arm pain; nausea; sweating; dizziness and unusual fatigue. For men it is predominantly chest pains, discomfort, pressure or a combination of the three. They may also, although less commonly, experience the same or similar symptoms to women, like nausea, shortness of breath or pain in the neck, jaw, or back.
9. Breast cancer kills 450 men in the United States each year.
In 2015 alone, it is estimated that there will be around 231,840 new cases of invasive breast cancer diagnosed in women in the United States. In the same year, it is estimated that 40,290 women in the US will die from the cancer. A woman dies from breast cancer in the United States every 13 minutes. Lung cancer is the only form of cancer that accounts for more death in women from a cancerous disease. Men are, however, 35% more likely to be diagnosed with prostate cancer than a woman is to be diagnosed with breast cancer. According to a study, taller women are more likely to get cancer. Although breast cancer is a common cause of death amongst females, heart disease is actually the leading cause of fatality for women.
10. Aspirin can save your life during a heart attack.
It’s true, your average, everyday aspirin can significantly increase your chance of survival from a heart attack, if chewed. Aspirin slows down the blood's clotting actions by lessening the clumping of the blood’s platelets. Platelets are the cells that clump together to form blood clots. Aspirin stops this by halting platelets from clumping together, therefore greatly siding in the prevention or reduction of blood clots. When taken during a heart attack, the aspirin will slow down clotting and decrease the size of the blood clot that is forming during the attack. Following a heart attack, the ingestion of aspirin on a daily basis may help to prevent a future heart attack.
11. Men are struck by lightning 5 times more often than women.
Between the years 2006 and 2012, 82% of the people killed by being struck by lightning were men. Of those recorded deaths, 52% of the female deaths were while performing regular, daily routine activities, whereas the vast majority of the male deaths were recorded during leisure activities. Some researchers’ explanation for the disparity between the sexes is that males are unaware of all of the dangers associated with lightning and are therefore more likely to be in potentially vulnerable situations. They are also found to be unwilling to be inconvenienced by the threat of lightning. If in contact with lighting, go indoors, avoid shelter under a tree and, although not ideal, stay in your vehicle.
