Is this a job fit for a woman?

I'm an Appeals Specialist for a health insurance company. I investigate and review claim grievances in accordance with Medicare federal regulations. My wife says that this is a job fit for a female. There are guys that work in the office but I am the only guy on my team. I'm trying to guess why she thinks this way. Is it because I work with all women? I mean her father is a nurse so I don't get it. I have a chronic illness (MS) so I can't do something that's too strenuous physically. Is she right?
