RE:RE:Restore the boardZorg ...off subject. Wife and I in that highest risk group as well. Over 70, very high BP's, three BP meds in her case to stay just under stroke risk territory. Both of us because of covid shortages for workers in pre retirement jobs are back now working near full time. In areas requiring contact with numerous people. Wifes in hospice and home health where shortage of RN's in our area is critical from nurses sick themselves. Taking daily doses of15,000 ICU's of vitamin D3. zink supplement , muliple daily C's 1,000 mg each plus some organic tumeric. She has been exposed directly to 4 people testing covid positive. One extremely sick where she was with the person over two days where he was in critical shape about to go on a ventilator when nano particle silver in a nebulizer was tried and his breathing cleared up A none standard treatment last resort. Did that do it? Doctor can't say for obvious reasons . She was exposed to co workers or patients in 4 cases. Wifes results after exposure ? Never tested positive after or during the exposures. No symptoms pretty crazy. Pretty proud of her for taking up the slack when called on! And is still at it. Simple things seem to be working as protection. Hope this helps and hope you stay well!
