Yet again posting here about boring contract stuff. I have the worst luck with contracts, and I need help understanding what this means for me if I accept this contract.

Here's what it says:

Employee recognizes that the various items of Information are special and unique assets of the company and need to be protected from improper disclosure. In consideration of the disclosure of the Information to Employee, Employee agrees and covenants that for a period of 3 years following the termination of this Agreement, whether such termination is voluntary or involuntary, Employee will not directly or indirectly engage in any business competitive with [Company]. This covenant shall apply to geographical area that includes all of the state of NJ, the City of Philadelphia, PA and the surrounding cities. Directly or indirectly engaging in any competitive business includes, but is not limited to [i] engaging in a business as owner, partner, or agent, [ii] becoming an employee of any third party that is engaged in such business, [iii] becoming interested directly or indirectly in any such business, or [iv] soliciting any customer of [Company] for the benefit of a third party this is engaged in such business. Employee agrees that this non-compete provision will not adversely affect Employee's livelihood.

Now I've read about blanket Non-Compete's that protect a business but aren't going to be enforced by a judge unless it is specifically violated. This seems to be a very unfavorable clause for me, because I live in South NJ, and basically all of my job prospects are in the Philadelphia area. This is how I make my money, so basically they're telling me I couldn't do what I do for 3 years after I leave the company. I'm fine with it as long as I can become an employee anywhere else, because I have no interest in starting a business or stealing theirs, but I don't want to limit myself as an employee.

With the above taken into consideration, would this come back to bite me in 3 years if I sign it?

Thanks for your replies, I know this is a boring question, but I need to understand what I'm agreeing to.
