You're right, Jane. Nothing beats whole (organic when possible) foods, lots of good water, regular exercise, and a cheerful, positive outlook on life -- and Transfer Factor which can bullet proof one's immune system.
Before I met TF, the herb cat's claw was my own first line of defense, more powerful than garlic, noni, aloe, echinacea, etc. I would brew up a pot of the stuff, let it steep, sweeten to get it down, and finally drink. Sometimes it would only take one pot of cat's claw tea to deal with a known invader. With TF I just pop a pill (ugh -- what a price to pay for boundless health) and the little bugger goes to work alerting my immune system of a potential pathogen, putting my own self-defense system on guard, and thereby assisting my own body to fight off ANY invaders, be they bacterial, viral, parasitic, fungal, etc. "Nearly everything that goes wrong with us, with the exception of trauma, can be traced directly to an immune system failure."
