Is it possible to never get sick?

yes and no

why well if you wash your hands really good almost all the time when u dont touch anything the sickness isn't really coming for you but if u are hanging out with some friends and one of them is getting sick and u dont know it u can catch it so basically No

No

Explanation:

There will always be a time where your body will not function properly, Even if you are healthy, what causes you to feel sick is thanks to pathogens, And once you start getting older your immune system will start getting weaker, causing you to be more vulnerable to sickness.
