I've been thingking for years to create a system where chemical changes in the body can be examined and introduced in a big database.
Well, the concept is to create a hardware that can be attached to the body and analyze the spectral signatures of the entire chemical composition of the body and create a file that can be send wirelessly to an internet server. There, in the internet server that information can be analyzed and minned to extract knowledge.
It could be possible to know if in certain diseases of even aging, the body composition changes.
Could be possible that in Alzheimer disease could be present some chemicals in the brain that in healthy people is not present?
That could be one of thousands of questions that we can ask. It's information based on data, not based on opinions.
