If you think of guys with gray hair as uncles, think again. I think there is a certain je ne sais quoi about gray-haired men that I really dig. Perhaps it has to do with the liberal peppering of gray that my husband sports currently but I have come to regard gray as good! That pepper-salt hair seems to indicate a bit of wisdom, speaks of a life well-lived and a certain self-confidence that indicates a man who is at ease with himself and feels no need for artifice.
