Does Cholesterol Intake Perhaps Relate To How Annoying A Person Is?
My grandpa is grouchy and obnoxious, and he eats all the hot pockets, expanding his already massive-waist line. So could “fatness” in a person be a factor for determining how annoying their personality could be?

I performed an extensive search on a number of medical databases, and I couldn’t find any double blind randomized controlled trials to support or refute your hypothesis. Perhaps this could be an interesting trial for you to undertake yourself.
There are two types of chemicals in brain – 1) white blood cells – WBC 2) red blood cells – RBC ,red blood cells keep the brain sharp and strong
when a person becomes fat , the quantity of WBC ( a kind of chemical in brain ) increases , since brain controls the entire body , increase in WBC reduces the brain’s remembering power and also slows down the blood circulation in the entire body causing laziness
as a result , a fat person becomes lazy, short tempered , frustrated, tense , unforgiving, very depressed , socially unadjustable or in your words grouchy and obnoxious
SOLUTION – help him reduce his weight or problem continues
OR
there could be another problem with your grandpa , since he’s very old , all the excitement of a person dies in this age , this makes their life very boring and meaningless , they want to live more but their life is not worth living – they can’t accept this harsh truth ,all this causes frustration and anger which makes them grouchy and obnoxious
SOLUTION – if this is the problem with your grandpa , then i am sorry to say there is no solution except death
lmao aww. my grandad is big and quite grumpy too sometimes but i know it’s not related lol. try restricting his high calorie foods, THEN you’ll see him get nasty. hell, when i’m ancient i’m gonna eat like a pig; it’s not like it will matter lol.
