1. The total weight of bacteria in human body is 2kg
Humans have trillions of bacteria in them. In which could amount to about 2kg (this could be more and not less). Take for instance, humans has about 40,000 bacteria in the mouth. This is not to scare anyone but the fact is that human might not be able to survive in a bacterial-free environment.
2. People with blue eyes are more sensitive to pain than others
Colour of the eye ranges from brown to light blue. There are blue, brown, gray, green and red. In a research presented at the American Pain Society’s 2014 annual meeting, anesthesiology professor Inna Belfer, MD, PhD, presented findings suggesting women with light eyes may have a higher tolerance for pain. The research subjects were women who had undergone labour. Though still debatable as men might not really fit in to this.
