For a number of years now, Rapha, a clothing manufacturer, and Strava an online data tracking service have held the Festive 500—500 kilometers between December 24th ad December 31st.
Here are 10 images that defined the riding for me. It’s a great way to divert my attention from the stress of the holidays and a last great challenge before winter really sets in (usually). This year’s edition was also marked by the poignant loss of Tom Palermo, a cyclist who was hit by a driver in North Baltimore. His death shocked the cycling community in Baltimore and led to a memorial ride attended by perhaps one thousand riders, including myself. The loss, which happened midway through the challenge, made finishing all that more significant, as a proof of life, if nothing else.
Okay, I’ve been watching The Newsroom & House of Cards and thinking about Enemy of the State and thinking about the government that exists just below the public surface and wondering, just how big(rogue) it is. Is it small and focused on bad guys or is it unwieldy and looking at people’s fantasy football stats? Either way, just realizing that assuming it matters, despite what is said by top officials, nothing electronic is truly secure … Not that I truly care. Because if someone is monitoring my email, I’d be happy to get help with that thing, you know what I’m talking about.
“All of this tells us the same lesson: Almost nothing we do on the Internet can be protected from government prying and spying,” said Michael Ratner, a U.S. lawyer who has worked for anti-secrecy website WikiLeaks.

Dr. Walker said he suspected that one factor that plays a role is a substance called adenosine, a metabolic byproduct that disrupts neural function and promotes sleepiness as it accumulates in the brain. One of the ways that caffeine stimulates wakefulness is by blocking adenosine. Adenosine is also cleared from the system when we sleep.
Without enough rest, adenosine builds up and may start to degrade communication between networks in the brain, Dr. Walker said. Getting sleep may be the equivalent of rebooting the brain.
“I think you have about 16 hours of optimal functioning before the brain needs to go offline and sleep,” he said. “If you go beyond these 16 hours into the realm of sleep deprivation, then those brain networks start to break down and become dysfunctional.”
Dr. Walker said it was increasingly clear from the medical literature that there is not a single tissue in the body that is not beneficially affected by sleep.
“It’s the single most effective thing people can do every day to reset their brain and body health,” he said.
