Great suggestions.
People helping others should not forget themselves. Although Blast is far more knowledgeable than I am in prepping, there is no harm in reminding him and others to take supplements (multivitamins ..etc.) to boost his immune system.
Not only do I take supplements, I started my own line,
Medicine Man Plant Co., back in January of 2020!
The Immune Pill and
The Brain Pill got me through the adventure. We were also required to be N95-masked at all times, hand sanitizer was everywhere, and I was constantly wiping everything down with beach. Everyone coming in had their temperature taken and we had a special area set up for potential Covid patients.
