Corollary to the "fifteen minutes" rule

I've read about some theory that says that it takes fifteen minutes before one starts working with full concentration. I can't actually find a good reference to this theory, but here's an article that mentions it.

I've been thinking about what that means for tasks that take less than fifteen minutes to perform. Or for writing that takes less than fifteen minutes to read. Or so on. If your brain is only half-engaged for these things, is there really much point doing them? Read a book instead of one hundred short news articles online. Devote serious time to problem solving rather than fixing niggles (until niggles are all that are left, of course). Write a book instead of a blog.

Because there's always something that will take more time than whatever you're currently doing.


Autism vs. Vaccination

The paper that, apparently, started the whole movement against the measles-mumps-rubella vaccine has been withdrawn by the journal in which it originally appeared in 1998. Not only have its suspicions been very much discredited by subsequent scientists, but its principle author acted unethically in both his approach to science and his reasons for publishing the paper. Dastard.

I find it terribly, subtly tragic that I know people younger than me who have had measles, which I hope to see it eradicated before I die. Disease eradication is in my list of ideal traits of high civilisation. Anti-vaccination mongers ruin everything.
