71 years young
I have been using TianChi for lunch with a few almonds. When I am bicycle riding on longer rides, 50-80 miles, I have one bottle with TianChi that I sip along the way along with water in my other bottle.
I am now about two years into LCHF type diet so TianChi is really nice for the longer rides. I’m 71 years of age and still working in my private office every day as a Physical Therapist and riding my bicycle 200 miles per week. I really enjoy TianChi!
