Anyone else worried about getting sick before their surgery date?

My surgery is scheduled for 4/4/02...I am petrified of getting sick before then, especially since I haven't had a cold all winter. I feel like I might be jinxing myself! Any ideas on how to make absolutely sure I don't get sick in the next two weeks?
