Pressurize moment

P=pXgXh

Where,
pressure is P,
the height is h,
density is ρ,
gravity is g

Let
P=pressure created by an issue
p=complexity of that issue
g=importance of that issue
h=magnitude of that issue

Hence absolute mental P at any given point of time = Summation of all P (ie all issues on hand at same moment of time)

Also P=F/A ie Force/Area

Let,
A=mental area
F=acting mental force to endure pressure

Hence F=PXA ie higher P means higher F
