Yang Family Tai Chi Discussion Board

I recently saw an acupuncturist/chinese doctor who said to me that I am now "more grounded and not floating as I used to be". He did not explain what he meant by this and I cannot seem to find information about this. Can you help me out? I really want to know what he meant by this. I've been seeing this doctor now for almost 2 years and it's just difficult to understand his English and he doesn't explain things very well. Do you know what he meant by this? Any suggestions would be great.
Thanks,
Christina
