I remember when I was a kid (about 30 years ago) twice a year a big blue truck would come to our school to give us audio (ear) tests and eye tests...make eye glass prescriptions and do basic ear wax removal from ears. Years later at college and in a different state, there was a doctor's clinic, dental office and other health facilities "on campus" for university students only. Years after that, in another state, it was common to see large size companies with "in house" daycare facilities (usually on the first floor) for employees. I remember thinking back then why wasn't such universal across the U.S.
