Ever noticed how some people always seem to falling prey to cold, be it summers or winters? It may be genetic, and now a leading science writer, Jennifer Ackerman, busts some other common myths about cold in her book 'Ah-Choo'.

You can't catch a cold by kissing: a kiss won't give you a cold. The largest family of viruses causing colds are rhinoviruses, and these rarely enter our bodies through the mouth, according to research at the University of Wisconsin Medical School.
