Couple of things:
First of all, you're 42 years old? For f'ucks sake, man, that means your daughter is legal. What's up with the complete lack of an introduction?
On to the meat...
Becoming a merc is a dodgy proposition, at best. If you are able to get past the ethical questions and the moral dilemma presented by becoming basicly a hired gun, you must accept the fact that like so many Haliburton truck drivers and NYT reporters, you have 0 protection from unsavory characters outside of the side arm you will likely be carrying.
Not having been a soldier myself may cheapen the opinion, but I believe in the romantic notions of honor in life, honor in death. A mercenary tends to be one without honor. Is it worth it to make a couple extra bucks?
