You may have heard rumours that deodorants and antiperspirants could cause breast cancer. But these concerns were started by an e-mail hoax. There is no convincing evidence that antiperspirants and deodorants cause breast cancer. Why are the claims about deodorants and breast cancer wrong? The original e-mail claimed that antiperspirants stop your body from sweating out poisons. It suggested that these toxins build up in the lymph glands under the arm and cause breast cancer.
Sharks Have Been Around For Longer Than Trees. The earliest sharks swam through Earth's oceans around 420 to 450 million years ago, a time when there were no true trees on land. Paleontologists can trace the history of sharks this far back by examining fossilized shark teeth and scales.
Female bull sharks have a longer lifespan of about 16 years, compared to 12 years for males. There is no accurate data available about how long a Bull Shark can live to. Howevâ¦er, they are known to live to ages of around 15 to 20 years. They reach full size and sexual maturity at around the age of 10.
