Baojun Yuan, the man pictured above, learned Photoshop at 60 years old. He's now 76 and for the past decade or so has repaired over 2000 damaged photos and done it all for free. Yuan bought a computer and scanner himself and doesn't charge people because he jokingly says, "My teacher just taught me how to repair the photos, but he forgot to tell me how to charge". What a guy.
I hope he has a better computer now though
