I am 76 and have a low immune system, AFIB, COPD, Asthma, Sjogren's, orthostatic blood pressure (it goes up when I stand) and numerous other illnesses. 2 years ago after being admitted to the hospital every other month, I was in trauma 1 and in very bad shape. My pulmonologist told me to wear a mask all the time when I was out and to not shake hands or hug people (I was a hugger). He said the next time I was admitted, I would be in for at least 2 weeks. I started wearing a mask and following my doctors very difficult orders, and I have not been in the hospital. I wear cloth masks and paper masks. With all my heart, lung and blood pressure problems, the masks haven't caused me any problems. They have prevented me from having problems.
