And again!

I got in another tai chi workout at the gym, that's two for the long weekend!   I wanted to go yesterday but my legs were so sore.  Felt good starting out today but I fatigued before I even got to the long form.  I had Mom do the 18-style with me.  She did as well as expected, I had a chair ready for her to sit but she almost finished. Then I barely got through 1st section, so I took 2nd section in bits.  I'm wondering if the new thyroid med isn't tiring me out quickly.
