for years we have used surveys to prove almost anything and there have been thousands and thousands of them that were wrong. How many times have drug companies used trial and surveys to prove there drugs on for it to be proved later that there info was wrong. I always like to say I can prove anything with a trial run or survey.
The latest thing now is for someone to write a program that can prove any and everything. I think it is the same thing you can write a computer program to prove anything.
The idea that any program on a computer can tell your age is stupid.
Maybe they should try it on the Olympics girls from china and prove there age.
I think the old garbage in garbage out about computers will make this program only so good but not good enough to prove a person age say 90 percent of the time
