Your Brain consists of about 100 billion neurons. That's about 166 times the number of people on the planet. 10,000,000 of the cells in your body will die and be replaced with new cells. All while you've been reading this. Calculating DNA length for each person, it would stretch across the diameter of the solar system. If the information contained in the DNA could be written down, it would fill a 1000 volume encyclopedia! Your brain is capable of having more ideas than the number of atoms in the known universe.

One human brain generates more electrical impulses in a single day than all of the world's telephones put together. We share 98.4% of our DNA with chimps. In comparison, we share 70% of our DNA with a slug. Our bodies are recreating themselves constantly. We make a skeleton every 3 months, new skin every month. We are capable of reversing the Aging process! regards, Lalitha.
