Dreams occur in the Rapid Eye Movement (REM) stage of sleep. We tend to remember the dreams that are seen just prior to waking up, but often the experience of time during our dream and awake stages is skewed.
Swedish and German scientists studied Lucid Dreamers(People who are aware while dreaming and are able to control the dream) and found out that there is a negligible time difference in non-physical tasks done in the dream stage vs in reality.
Physical tasks, like running, took longer in dreams than in reality.
Food provides the cells in our bodies with their fuel: glucose. Our bodies release a certain amount of glucose into the blood and store the rest as glycogen, releasing it as needed. Once that supply is used up – after at least 12 hours without food – our fat stores are called upon.
Burning of fats actually makes the body less hungry, something which is being researched by dieticians studying metabolism. It is also observed that fasting dampens certain types of hormones, reducing the risk of breast cancer.
It is a mathematical theory stating that we are bound to be less popular than the people in our network of friends, especially the online one. This hypothesis is easily checked in social media accounts like Twitter and Facebook.
The people that we follow on Twitter, for example, aren't always following us back and therefore end up having more followers than us.
Laughter is a form of social bonding because it is contagious and allows us to show that we are non-threatening.
We laugh when we see or hear something funny. We laugh to show that we are being silly.
