<span>Collin often experiences a "runner's high" during his daily three-mile run. this is most likely produced by endorphins.
Endorphins are related to a group of hormones which are secreted within the brain and the nervous system, it is like morphine chemicals which are produced. It is mostly produced when you exercise a lot, run high or stress etc.</span>

Homo sapiens means wise human being, it one of several species grouped into the genus Homo, but it is the only one that is not extinct. It is the specie where all human beings belong. They replaced Neanderthals during 30,000 BC. Scientists believe that Homo sapiens appeared in Africa between 150,000 and 200,000 years ago.
A natural phenomenon that typically influences climate over a period of one to two years is sulfur-rich violent volcanic eruption.
Without any doubt, the most plentiful volcanic gas from a volcanic eruption is water vapor, which is non-dangerous.
Nevertheless, notable volumes of carbon dioxide, sulfur dioxide, hydrogen sulfide as well as hydrogen halides can also be released from volcanic eruptions. This natural phenomenon generally influences climate over a period of one to two years.
The sulfuric acid creates a mist of minute droplets in the stratosphere that reflects the incoming solar radiation, an thus is responsible for cooling of the Earth's surface.
These droplets can stay in the stratosphere for about three years, circulating all over through winds and resulting in consequential cooling all over the world.
