MRSA can eat a kid's foot right off you know.
> MRSA is becoming a critical problem in pediatric settings;[38] recent studies found 4.6% of patients in U.S. health-care facilities, (presumably) including hospital nurseries,[39] were infected or colonized with MRSA.[40] Children (and adults, as well) who come in contact with day-care centers, playgrounds, locker rooms, camps, dormitories, classrooms and other school settings, and gyms and workout facilities are at higher risk of getting MRSA. Parents should be especially cautious of children who participate in activities where sports equipment is shared, such as football helmets and uniforms.
Hmm ... guess not. Sounds like running around San Francisco barefoot is actually safer than doing anything at all in day-care or a sports club O.o
That said, I used to run barefoot all the time. Even in San Francisco. Never got any wounds or infections. After a year of practiceb even stepping on glass didn't pierce my skin.
