This site contains
publicly confirmed fundamental information
stated through my sites back in the COVID pandemic
(and there are many witnesses to this in the world), by doctor on
the specific one (witnesses from the whole district)
and reverified by at least the 2nd load
(cold/all COVID seasons I went through the winter in a shirt
with a warm T-shirt + above average physical jobs/there is
a photo + a small child + major repairs + constant insults)
of several flu epidemics and all years of COVID
(without masks, isolation, restrictions and vaccinations)

TRUE/REAL NATURAL IMMUNITY
for a real healthy lifestyle / HLS (separate sites)

If you are interested in strong (and this is only natural) immunity,
then, believe me, you will have something to seriously think about,
what with that to compare and decide how and where to live next.

NOTHING  MORE  SIMPLE  AND  PROFESSIONAL,
IN TERMS OF NATURAL  IMMUNITY, AND  MORE  PROVEN,
THERE  IS  NO  IN  THE  WORLD / INTERNET YET
