You should care about your DNA! It isn't just a blueprint, but a computational device that stores an insane amount of state information. In fact, the internal state of your cells as an aggregate (genome/proteome, concentration/expression levels, modifications, etc) hold far more state info than mere synapses. I understand that we all view our brains as a record of our cognisant experiences. However, there is far more at play at the molecular level than non-biologists usually consider. Brains are not magical "higher level" abstract devices. They work in concert with the existing computational machinery of the cell and the genome. If you don't buy that argument, at least be mindful that if you don't take adequate care, you will increase your probability of getting a cancer that your immune system cannot fight. Your cells are critical. Your gut flora is critical. You are an ecosystem, not an individual. Your mind is only the deterministic imprinting that the physical world makes on you as you make your way through life. (I'm a computational biochemist and soon to be systems biology student.)
