My name is Jules Roberts, a former owner of an ambulance company and EMT. Going in and out of hospitals for over 20 years, I learned to stay healthy, I had to constantly wash my hands and wear light-weight booties over my shoes when entering contaminated rooms.
The ER doctors explained that our hands and feet carry many germs and they will generally spread many diseases and viruses. So I was always washing my hands and cleaning the bottom of my shoes with an alcohol spray. I guess I was ahead of my time. Today everybody is doing it. For years I have been telling people to take off their shoes before they enter their home. Some people listened, but most did not.
