When I was younger, I often went to donate blood. And he was a good donor. I felt that I was doing this for the sake of good and useful deeds. I like to help people. Now I'm over 50 years old and I don't donate blood. Thank you very much for an interesting and useful post. Good luck and great success in your business. I read your posts with pleasure, when you bought a lot of land and lived in Spartan conditions, doing rural work, it was great. You are a strong person.
