For some reason, PS fluid tends to break down after certain miles. It will cause your PS to squeek when turning, which is a bad sign. For my car, the PS pump actually failed and I lost PS in mid driving. It was quite difficult... This is an easy fluid change, and it'll definitely be beneficial to anyone with a high milage vehicle. Mine failed at 30K.. so yea...
Just make sure you use the Honda Specific PS Fluid.
