Kingtrumpet, do not confuse ailments of tendons and ligaments which you describe (albeit the gout and psoriatic arthritis are more in the differential of inflammatory disease) with NORMAL muscle function. A healthy long distance runner knows that they can get just as much performance on a morning run than an evening run. This is because they are working healthy muscle. The same is true about trumpet players, as my mantra is muscle [healthy] is muscle [healthy]. Good toned healthy lip muscle will respond to a good warm up no matter what time of day demand is required of them. I myself never have found a variation in my performance level that relates to time of day, as long as my brain if alert and functioning and I have had the right amount of rest. So do not confuse our readers with the poorly toned, arthritic invalid (Kingtrumpet) with the highly toned, athletic performers (everybody else on TM). We don't want any of the newbies here thinking they half to start out like the old decrepit KT.
