I know that
Ray kurzweil would like to live forever. I also know he has a relationship with a business that sells supplements, although
supplements is probably the wrong description. (I think that's the right website) ... Notice the cost of the supplements, this is usually an indicator (to me) that it's more about what they can make out of it than how good they are for you. By the way I understand that Ray constantly checks his constitution medically, and adjusting the supplements accordingly. So the supplements he (sells?/is associated with) might work for him, but may not work for you, unless you go through the rigmarole of being tested and having the supplements/drugs whatever adjusted to your constitution. Hence my dubiousness about the reliability of supplements...
Ray's idea of living forever is not quite as daft as it might sound, although I suspect it's a bit tongue-in-cheek. Basically every year "they" manage to extend life expectancy. Every year, they manage to extend it just a tad more. There will/may come a day when every year, life expectancy is extended by one year. In other words you are at a point where immortality is no longer impossible. Hence Ray is interested in anything and everything that can enhance his life expectancy. So I would surmise that the drugs chemicals whatever he is associated with would be genuine, however some may be somewhat out there. Ray is older than me, and I think he believes he has a good chance! I'm not too sure, and anyway I generally avoid taking tablets.
In my late teens I frequently got tonsillitis. The normal course of action was to have them removed, however my doctor, Dr Kennedy from Hungerford advise me not to have them removed. It has subsequently been proved? ... that they have the beneficial effect of providing a first line of Defence. In other words when your tonsils are inflamed it means your body is under attack and your tonsils are doing something about it. I have no idea if you are at more risk of infection if you don't have your tonsils, but I can see the sense in keeping them! This translates to me to, my body knows what it's doing, let it get on with it.
Ray is a very clever man and has predicted accurately many things about the future, particularly in his books like this one:-
"The Singularity is Near"
I went to see him present in London, and shook his hand. I also received a signed copy of this book!
