There's a massive risk factor for any respiratory infection.
I have a friend (age 70, same as myself) with asthma. She and her husband got the real thing a couple of months ago. She said she had never been that sick for three weeks in her life - really bad.
Not long before that, at my suggestion, she began taking NAC, the dose of which she upped as soon as she became ill.
A couple of months after her recovery from c19 she sent me a note thanking me for the NAC recommendation. She said she had not had to use her inhaler once since recovering and is certain that NAC is the reason.
NAC in inhalant and IV form is used for asthma and respiratory problems. Perhaps it could have helped the man. Again, though, we just don't know what else was going on.
The wife and I have a 2 year supply of NAC on the shelf. My doctor said we were fine to take it every day. He was surprised to learn the it is available as a supplement OTC. He said it is also used for tylenol overdoses. Apparently, tylenol overdoses are common among attempted suicides. He told me that a tylenol overdose is *incredibly* painful. NOT the way to off yourself.
Mind my asking which brand/dosage you use/store?
