This is, with no intended disespect, both absolutely false and dangerously blithely ignorant.
Unfortunately most of the population (including medical doctors) also has a similarly nonchalant conception of mold; that it's something that merely causes some allergies and sniffles for sensitive members of the population.
Toxic mold secretes _neurotoxins_ which will 100% destroy your life for years, if you get a bad enough exposure.
Read some of the experiences of mold survivors in this thread or elsewhere to get a sense of how bad this can be: it's horror-movie stuff.
Source: been through mold exposure myself. It wrecked my life for 5 years, and I still have lingering aftereffects.
