Do you want to grow a beard?
Are there any outside factors in your decision to grow or not grow one?
If you want to grow a beard, and there is nothing stopping you, do it. Personally, I like my beard to be alive and well, but I will probably have to kiss it goodbye when I graduate in a little over a year, because for some reason, employers think having hair on your face means you are a horrible, horrible person.
When I get old and retire and no longer depend on anyone else to pay my bills, I plan on growing out the bushiest, largest beard you've ever imagined.
