hmm.....if I admire someone for doing something that obviously isnt real?
I'm sorry to shatter your illusions my friend, but i think you'll find that most magic isn't "real" - in the literal sense!
its all about the effort and showmanship you put into something that makes it special. And of course, David Blaine is a superb showman, make no mistake!
Your missing the point, I think there's an element of doubt as to whether David is really depriving himself 100% but let me make the point AGAIN! - its a stunt, for publicity...and whether you like it or not, its a pretty impressive stunt!
Do i detect a hint of jealousy after the comment about the fact David Blaine earns more in 1 lifetime than you will in ten? So what? if it bothers you that much, write in and complain to the people that pay him! I suspect your letter may take a one way ride to the shredder, but whatever lights your candle!
anyway, we, as magicians, whether we agree or not with his methods, should raise a little smile and acknowledge the fact that its a good bit of entertainment! And after all my friend, and this is the point you completely miss...WE ARE ALL IN THIS INCREDIBLE BUSINESS, MAGIC, TO ENTERTAIN! Not to take cheap shots at fellow magicians just because its easy to do so.
it might be an idea to get off the bandwagon and perhaps channel your energies into something more productive!
Good luck! And enjoy your magic,
p.s. Santa Claus isn't real either! Sorry!
