Short answer is YES
Ummmm
Yes
Its called immunity
I remember being a 6 year old and in my local park in Miami they had an old real choochoo train, and fighter plane you could play in! Those were the real days:-)
I worked construction all my life. NEVER washed hands before eating. I never get sick. Never had a flu shot.
I probably get the flu every few years or so but it is short, hard and rare.
No kid is allowed to get dirty these days . No wonder they are always sick.
Yep. It’s well-known that kids raised in rural areas or on farms or around animals and pets — or any such combination — are much healthier than kids whose parents (esp. mom) are obsessed with cleanliness. It’s crucial to keep one’s microflora, both inside (intestines) and out (skin), diverse.

A docmentary about Polio “The Polio Crusade” expressed one of the reasons Polio suddenly became an epidemic was because of modern sanitation and food prevented exposure of babies to many diseases WHILE they still had immunity agents which they got from their mothers.
They would at a later age get exposed when those natural immunities were gone and they had not built up their own.

Old Wives Tale: Unless a kid eats a peck of dirt by the time he is three, he will be sickly his whole life! Age of three might be wrong but concept is correct!
My personal opinion: All of the sani-wipes and such in use, tend to get rid of the weak strains and allow the stronger more hazardous ones more room to expand and contaminate.
