TED notes: how sleep removes waste, and “a republic, if you can keep it”

Jeff Iliff: One more reason to get a good night’s sleep

  • why is sleep so restorative?
  • sleep is an elegant design for the brain’s waste removal
    • the circulatory system provides nutrients to every body cell
    • every cell creates waste; the lymphatic system removes this but there are no lymphatic cells in the brain
    • how does the brain clear its waste?
    • brain has cerebral spinal fluid (CSF) which removes waste
    • CSF moves along brain blood vessels
    • this only happens when sleeping
    • when the brain sleeps, brain cells shrink, which makes room for CSF to rush through brain and remove waste!
    • when awake, brain is busy, puts off waste removal process until sleep
  • what kinds of waste?
    • amyloid beta (AB) — Alzheimer’s is the accumulation of AB, but this doesn’t prove a lack of sleep is the cause
  • sleep literally “refreshes” the mind!

Lawrence Lessig: We the People, and the Republic we must reclaim

  • USA is an imaginary Lesterland — there’s a general election and a money (the Lester) election
    • in Lesterland only the funders get to vote
  • 0.26% gave $200 or more, 0.05% gave maximum <— the tiniest slice of 1%
  • 132 Americans gave 60% of all Super PAC $$$
  • Congress spends 30-70% of time raising money
    • they develop a “sixth sense” of what those funders want
    • not popular issues 1-10, but 11 to 1000
  • funders don’t do it for public but for PRIVATE interest
  • Republicans might want small government, but for example if they de-regulated Telecoms, response was (after Al Gore proposal): “if we de-regulate them, how in the hell are we going to raise money from them?”
  • an “economy of influence”, feeds on polarization
  • Henry David Thoreau: “there are a thousand hacking at the branches of evil to one striking at the root”
  • solution: single statute, for a citizen-funded election
    • more funders, smaller amounts, less time spent on fundraising
    • this would shrink K Street
    • political staffers, bureaucrats are a “farm league” for K Street
  • Ben Franklin: “A Republic, if you can keep it”
