Hi,

I am long time photoreader more than 10 years.

What is the difference between Photoreading 4th ed. (2007) at
http://www.amazon.co.uk/gp/product/09254...&sr=8-2&seller=

and Photoreading 3rd. (1999) at
http://www.amazon.co.uk/Photoreading-Whole-Mind-System/dp/0925480533/ref=cm_cr_pr_product_top

Thank you in advance. Wish you very happy new year 2010 and bring all the successes you deserve with this photoreading skill.

Mike
