Hello, I'm Crystallizedcarbon. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Altitude training— because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Crystallizedcarbon (talk) 19:09, 15 March 2016 (UTC)
