Radiator Hoses - Routine Replacement?

[bplaney]

I'm going to replace my serpentine belt over the next couple weeks. I've decided against replacing the water pump until (hopefully) the next timing belt replacement. At 109k miles, should I replace the upper and lower radiator hoses just because I will be flushing out the old coolant, so why not? I have no idea from the meager pile of service receipts that came with the car when I bought it at 97k miles whether those hoses were ever replaced. Is there a way to tell how much life is left in them?
