. I have taken zinc for about 10 years with “over 50” vitamins. I rarely feel effects of a cold.

Same here.
Plus getting in as much exercise as I can and eating well. All the normal stuff to keep healthy, which is the best way to be resistant to all forms of infectious diseases not just coronavirus.
