You’re Never The Same You!

“The measure of intelligence is the ability to change.” —Albert Einstein

In the second edition of my book on Cosmic Consciousness, I discussed in some detail that your physical body undergoes rapid and extensive physical change. The April issue of Scientific American puts some additional quantification on this point.

Body Mass

25 percent of your body is fluid outside of your cells, e.g., plasma.
7 percent is solids like minerals.
68 percent is made up of human cells.

Number of Cells

A 70-kilogram person has about 30 trillion cells.
Fat and muscle cells are large—72 percent of your cellular weight—but only 0.1 percent of the 30 trillion cells.
87 percent of your 30 trillion cells are red blood cells, which are quite small.

Daily Change

By number—You lose and regenerate 330 billion cells every day.
- 86 percent are blood cells.
- 12 percent are gut cells.
By weight—You lose and then regenerate about 80 grams each day.
- 49 percent are blood cells.
- 41 percent are gut cells.
- 4 percent are skin cells.
- 4 percent are fat cells.
- 1 percent are muscle cells.
