Haven't posted in a while but been waiting to chime in on this subject. I've been in most of the major airports the last 2 years and traveling all over the US. Never had any issues. Sniffles and a headache maybe?
I take:
Quercetin Vitamin D3, C Elderberry Zinc Turmeric Ginger Echinacea L-Lysine HCL Black cumin seed oil
At the end of the day exercise and taking care of yourself is the best you can do. We don't hold people responsible for their own healthy choices and habits now a days in the US. Sad times. Instead of "You didn't take care of yourself" we say "I feel so bad for you Covid is such a killer!!"... You can't eat Wendys and smoke cigarettes every day and be guaranteed "healthcare". Actual healthcare is how you take care of yourself. People depend on pharma but they're kidding themselves.
