Nice. Being a tall person spring mattresses hurt my back. Ever since I switched to a waterbed my back doesn't hurt when I wake up in the morning. It helps some people. Some people don't like it. That and I drink body builders Whey Protein powder for athletes and it helps rebuild back muscles really fast. That reduces your need for other stuff. There's no single answer. It takes a lot of little ones. Know your limits too. But, the powder drink makes my back feel better by the next day instead of 5 days later. Waiting for my computer to save my next video. It's so slow. 3 hours to make, edit and process a 23 minute video.
