As I recall, viruses aren't treated with antibiotics. The strain mentioned in the last link is resistant to the immune response generated by current vaccines. It may seem like a small distinction, but people demanding antibiotic treatment courses from their doctors regardless of the actual infecting agent is one of the reasons we have such a rapid spread of antibiotic resistant bacteria.
"...that an overwhelming percentage of adults over age 45 develop far-sightedness?"
IANAOptometrist, but having worked in an Optometrist office for several years, the line we gave to our patients was that presbyopia was simply a by product of aging, and not really far-sightedness per se. This is why you see older people who previously had poor distance-vision with bifocals, trifocals or progressive lenses, they need different levels of correction for objects at a distance, fine detail up close, and for extensive computer users something in between. There are some computer or executive type progressive lenses on the market, but these simply sacrifice your distance prescription, and give you an intermediate-to-near prescription gradient.
