I just eat with dirty hands. No matter how hard I try to be clean I will always end up consuming filth one way or another so now I dont worry about it. I'll take a shit, not wash my hands and then pick up a slice of pizza no worries.
You go around with shit particles on your hand, infecting everything. You're a typhoid Mary. Even if you've never been ill after eating some food (which I find unlikely) it's not unlikely that you have made people ill, and maybe even killed someone with a weakened immune system.
Up to a quarter of a billion people are infected worldwide, in large part due to poor hygiene.
Then there's round worm, likely a billion people infected globally. Once again, due to poor sanitation and hygiene aka handwashing.
But hey, you do you.
Just know that at this point you might as well stick your thumb up a strangers ass then lick it. It's fundamentally not that different to not caring about washing off shit particles before eating food.
Look at the difference in sick days between a construction worker and an office workers. Spending your whole life trying to avoid germs is a futile battle.
