Not quite warm enough yet

I really can't wait for warmer weather to get here! Today it got up to 45*, which actually felt pretty good after the cold winter weather, but I still want it to get up in the 70's sometime soon. We have our thermostat set to 70* (I'd like it warmer, but trying to save money) and I'm sitting here cuddled under a blanket. I get achey when I'm cold too. I don't have rheumatoid arthritis, but I might have psoriatic arthritis, and when I'm cold my knees, wrists, and fingers get very achey. The baby is taking a nap right now and the boys are being good so I may go take a hot bath to warm up.
