[Closed] Should I take up Boxing?

Sat in the gym Sauna last night and I was talking to a group of Manc's. They all box at amateur level and they all agreed and urged me to take up boxing.

I did mention that if they wanted to kick the **** out of me they could just as well do it here rather than wait to get me in a ring (they laughed I was alittle nervous still!).

Girlfriend thinks its a bad idea, saying head taking a knocking etc etc. They reckon its good for fitness and fun etc.

What do the STW massif reckon?
