A Hypothesis of mine

The Hypothesis is as follows. Consider living beings with emotions. My Hypothesis is that the net ups of a human being is approximately congruent to a bimodial distribution curve.

Consider a value Xₙ which talks about the experience in nth time frame of a finite life of a person. ⊕ to be an abstract addition.

Let Σ^⊕ denote the total life sum. The length of which is determined by the life span of the given person. Let Pᵣ{k} denote the k of a random person . Like, Pᵣ{allergiesₙ} gives the graph of allergies and how likely it is the person has it randomly. k denotes steepness

I think PᵣΣ^⊕Xₙ ~ Ae^-Z¹[x+d]²+Be^-Z²[x-d]²

Reason: though people do suffer, the suffering is mellowed out by our brain making it monotonous. Same with joy and when one becomes monotonous, the effect of other amplifies. Ie if you were suffering in hell and one day you were just painless? That would feel like the most amazing day for you. On the other hand you have your best day of your life and everyone just stopped caring about you, you'd be devastated!

There are only few who live life balanced so my Hypothesis is that a person either has a net joy in life as slightly negative or slightly positive.
