I have come to realize that the physical and mental self are two different beings.
Almost independent.

The physical self seems to have no mind of its own (no pun intended)
It loves to sleep
It loves to eat
It loves to laze
It love comfort

The mental self clearly has a mind of its own, but suffers from severe peer pressure and social influence
What will the world say
I know I can do this but am I good enough
I should eat this; I shouldn't eat this

Overtime, the biggest realization is that the mental self's thoughts are extremely contagious
To your physical self
And to other mental selves

In other words,
How you think
Influences your physical self
And influences the mental selves of others

If you now know that you are the source of a "virus",
What would you choose to spread?

Hat tip: calm is contagious
