Shareholder update - goodbye GSK toothbrush?, page-99

I can personally understand why GSK only tested the manual toothbrush on human subjects using the brush for 30 seconds:
1. I have always been a shocker/lazy when it comes to brushing my teeth. For most of my life, 30 seconds with the toothbrush would be a long time. I suspect GSK knows that the average punter is just like me and have to adapt to the human psychology - 30 seconds is all we've got.
2. Recently my dentist implored me to get an electric toothbrush and that it will work wonders with my tragic dental situation. I did just that - bought an Oral-B pro-3000. I've had it for three months. Have kept to the instructions every day (30 seconds use in each quarter of mouth - 2 minutes in total). It's been amazing, but I suspect that I've formed the habit of using it for 2 minutes (and abandonned my old lazy ways) is because the electric toothbrush does a damned fine job compared to the antiquated manual thing.
3. In conclusion, I can see why OBJ is much more focused on the electric toothbrush idea - both for timing (the human psychology will be different - consumers will spend more time with it in the mouth) and also the more powerful effect that the oscillations will give to the Magnetic micro-array tech.

Just my thoughts.
