Looking at a show called 'Doctor Oz', with the sound mostly turned down, I saw a Human Brain in a jar.
I thought of the knowledge, experiences and unique insight stored in each and every brain, and how this is lost forever at death, save for whatever is written down or recorded.
Some technology enthusiasts talk about the 'Singularity', the point at which we upload our consciousnesses into machines and exist forever.
I don't know about consciousnesses, but I look forward greatly to the point where we can save all these priceless experiences.
Only then will we have a strong culture which doesn't die with every citizen of that culture.
