Better yet if hoses are very old just replace them.
Too often a bad hose can look and feel good so best to make sure they are not old.
Most people freak out if they have old tires but yet they drive on 20 year old hoses.
I know that the prices on parts aren't what they used to be, and unless you are careful, the quality of general parts house stuff is not always top notch. But really, when viewed in the overall scheme of the cost of running an automobile, it just makes sense to me to replace a lot of stuff annually or at worst, every couple of years. This isn't always dependent on mileage, as some stuff "wears out" due to age more than due to actual use. Rubber, especially, can rot as fast or faster on a car that's not even driven! So when you are trusting tens of thousands of dollars and possibly your and other's lives to a mass of metal speeding down the road, why not spend a the equivalent of a few cups at Starbucks and replace hoses on a scheduled plan?
