The pool

Imagine if all feelings, everyone has could somehow be saveable or serializable, how would we better understand the human nature, what about their thoughts, ideas, how and where they had them, how they lived their lives in general. These details are so important compared to many other cold raw data of either basic, modern sciences or even literature, all these are just a product or result of how these people lived, what they faced, how they were raised, what feelings they had. If you have a record of all these you can easily restore states to make these scientific inventions or creations but using different people that have the same life signatures. Crossing from eye to eye as well as browsing brains would be the future human explorer, you would just have to remember that personal identifier or so-called name or dna or any other unique key to move to his brain using a series of peer to peer human brains, starting with your own brain and moving on to the next nearest human brain till reaching that person, the connection would be :) Upon successful connection you would be able to see his current thoughts, what he sees with his eyes as well as recent history of what he did, visited, thought of or felt, according to how public he left his brain profile you mightn't have access to some stuff :P
He might need a hand, why not? there would be some way to enable you to aid him with ideas, thoughts or refer him to use another recommended brain he could use...
