Not really, but The Real Hustle has done something very much like this.. Except that instead of a violin, they used a dog. :-) Video: http://www.youtube.com/watch?v=-Wy1P-XN328

You don't, go to someones feedback profile and under "Recent Feedback ratings" click the number of negatives (or neutral). That way you only see the negative feedback. I use this quite often because reading all the positive A++++ comments is indeed pointless.

Also Huntkey (power supplies and computer cases) and TP-Link (networking products). And let's not forget Romisen (flashlights). Zotac (cases, barebones, graphics cards) is Chinese too. Those may be some smaller companies (although TP-link can easily be found in local stores, at least in The Netherlands), but I do see a trend of products from Chinese manufacturers popping up in the west.

I don't believe M&Ms will help you teach him math completely. Counting? Sure. Subtraction? Hell yes. Everything else? No.

Maybe you should watch "How does your memory work?": http://www.bbc.co.uk/sn/tvradio/programmes/horizon/broadband/tx/memory/ and especially this part: http://www.bbc.co.uk/sn/tvradio/programmes/horizon/broadband/tx/memory/wiped/. Note that the video on the BBC website only shows a very small part of the actual documentary. In the full version, it explains an experimental way to make memories "softer". A memory would be saved in two parts: what actually happened and what you felt. It explains that when you recall a memory, the emotional memory becomes "fluid" and is re-stored, just like, in geek terms, your RAM needs to refresh to keep it's contents. Now the trick is they use a drug, ironicly I don't remember which one, that prevents the memory from storing properly again after it became "fluid". It's a regular drug that was made for another purpose but this is a side effect. So you take the drug, think of your bad memory, and the emotion connected to it fades a bit. But you need to go through that procedure several times, and it gets weaker every time. If I understood it correctly, the memory of what actually happened does not fade. It's only experimental, but it might be interesting for you to see if you can become a test subject if you feel it's worth a shot.
