That's a really good point about lasik. Great example thank you. But at the same time I guess it cuts both ways because lasik exists. but what I'm specially worried about is that cures might be designed to not be perfect so that maybe you need to buy them again in 15 years or something just like a light bulb they can make perfect light bulbs but they design them to be obsolete so they can sell more. Why would not the same economics operate in the pharmaceutical industry I think it's a tragedy that it might when they should stick with their hippocratic principles.
