Aching Legs

I'm putting it down to the change in temperature here. It recently got cooler (not cold, just cool). Having come from Australia it's slightly more of a shock to my system than it would be otherwise. My knees and left hip are aching. The muscles between aren't terribly happy either. Last night I needed an extra quilt before they were warm enough to stop aching.

I should check my warranty. See what my guaranteed operating temperatures are. ;)
