The medical myths

Common medical myths, even upheld by some physicians, torn apart by Rachel C Vreeman in the British Medical Journal.

  • People should drink at least eight glasses of water a day
  • We use only 10% of our brains
  • Hair and fingernails continue to grow after death
  • Shaving hair causes it to grow back faster, darker, or coarser
  • Reading in dim light ruins your eyesight
  • Eating turkey makes people especially drowsy
  • Mobile phones create considerable electromagnetic interference in hospitals.

Fair use quote:

A 2007 study, examining mobile phones “used in a normal way,” found no interference of any kind during 300 tests in 75 treatment rooms. In contrast, a large survey of anaesthesiologists suggested that use of mobile phones by doctors was associated with reduced risk of medical error or injury resulting from delays in communication.

The oil case

This TED talk is funnily enough entirely spoken from a US-selfish point of view. The already old presentation (2005) makes a scientific-economical, peer-reviewed case to get entirely rid of oil dependence for transport in a couple of years time, without major governmental influence and actually gaining (American) jobs. Not that the barrel price back then was $26, not the $80+ range we’re seeing today. It is a compelling proposition, and what it did to me is showing at least the real feasibility. Having said that, there is still, 2.5 years later no way for me to buy a truly fuel efficient car (Toyota Prius) here unless I cough up at least $42.000, and that is NOT the sort of car this guy is talking about.
