Need Surgery? Make Sure Your Surgeon is a Specialist

nock says...

Depends on the surgery. You don't need a specialist to do your acute appendectomy or cholecystectomy, but you DO need a specialist to do your knee replacement or ICA aneurysm clipping.

Also, I assume the risk reductions presented are relative - e.g. if mortality from a non-specialist surgeon procedure is 5% and a specialist surgeon mortality has a 4% risk, the relative risk reduction is 20% (absolute risk reduction is only 1%), which sounds really high and may be statistically significant, but in the real-world does not matter all that much. This would be called statistically significant, but likely not clinically significant.

How fracking works

nock says...

Sounds like a good argument, but 0.5% isn't nothing. Would you eat food that was 0.5% feces or insect? Would you like to die 0.5% earlier? Don't worry, it's almost all water and between 15-50% of the "acids" and polyacrylamide will be removed. That's up to half of 0.5%!

The Newsroom's Take On Global Warming-Fact Checked

nock says...

Trancecoach "In China and India (where pollution is no doubt a significant problem), there are hundreds of millions of people who have far bigger concerns and more pressing problems than some remote notion of a "warming planet" or some looming "catastrophic collapse of civilization." (In fact, the same can be said for the majority of the population of the planet.) "

Isn't that like saying the dinosaurs had bigger problems to deal with than an asteroid hurtling towards earth?

Old School Shoe Repair

nock says...

Well, for example, I went to a "shoe repair" guy when my soles needed replacement and the guy said he could repair them. When I picked them up they were horrible, the stitching was all off. The sole wasn't replaced. Basically old school is an art that is cultivated over years and decades of training and apprenticeship.
