Is it normal to never get sick?
Yep.Totally normal
Yes, it can be completely normal to rarely or never feel sick. You may avoid many infections, or have mild infections that barely register.
People vary in how often they get sick. Your exposure to bugs, your general health, and plain luck all play a part—and sometimes your body fights something off without you noticing much at all.
If you mean you can’t remember the last time you had a cold or fever, there’s usually nothing odd about that. Plenty of people go long stretches feeling fine; just keep up with routine care and vaccinations as appropriate.
