I doubt you can avoid kidney stones by bicycling or sports. Some are more vulnerable for kidney diseases like others. I wonder how you can rent a shop if there's no money? With us shops are extremely expensive, just the rent, next electricity, taxes. I am sure that with your talent the shop will thrive, you could also add painting lesson.
It means a lot to me thanks for such kind words and suggestions . Regarding my health, the doctor gave me antibiotics for my kidney treatment, which did give me some relief, but I didn't pay much attention to it after that. :-)
As for the shop rent, the expenses aren't that high in the area where I live. The total monthly cost is about $50, which I can cover with just two or three painting orders. To make things even better, I've already posted about my painting and calligraphy classes on other social media platforms. I'm hoping for a good response
