Am I overthinking this non-compete clause?

On Monday, I accepted an offer as a full-time marketing director for a small, privately-owned company that has existed for 20+ years. Today, the company sent me an "Employee Assignment of Inventions and Non-Competition Agreement." My understanding now is that this is a condition of employment.

My main concerns are: 1) that the company describes is business in very general terms, "business of developing and marketing health assessment and health promotion software, web-based health applications and products, and supporting health education materials." Most of the solution providers to healthcare these days could write exactly the same description. My marketing career has been in this area for the last 15 years. The non-compete term is for 2 years after voluntary termination. I am very concerned that I could be prevented from finding another marketing position in my field (healthcare solutions marketing) if I sign this. Am I overthinking the non-compete?
