My oldest daughter and her husband both caught COVID-19, were treated with invermectin and were symptom free within 3 days. You don’t want to wait until you’re really, really sick to get treatment. The same is true for HCQ. Zinc is needed in both cases. ZMA has a very highly bioavailability for both the zinc and the magnesium. It’s also pretty inexpensive, read cheap.
I never jumped one with a screwdriver but I had a Nissan Pickup in which the started relay crapped out and at the time I lived in a small town where the part was not available and had to be ordered. While waiting for the part I ran a wire from the starter that I could touch to the battery terminal and start the truck. I had an insulated alligator clip like you might find on a multi-meter on the end that touched the battery. When not in use I'd clip it to something plastic. After the new relay was installed, I left the wire attached.
