We have had a few posters here point out that to view viruses as simply “bad” and something to be fought is not a true understanding of the complexity around the subject. This is a very interesting study that finds the common cold rhinovirus, actually can help the body to prepare to deal with much more serious viruses such as 'flu.
A thought experiment: What would happen if we had a “cure” for the common cold? Are we opening up our society for millions more to die of 'flu instead?
