Is 64 the New 57? Probably Not!

Baby boom or bust … is 64 the new 57?

W E read with interest the article published in this issue of ANESTHESIOL-OGY by Orkin et al. 1 reporting on factors influencing retirement decisions by American anesthesiologists. The study employed a cross-sectional survey of anesthesiologists aged 50–79 yr, using a survey design to evaluate the decision matrix of retirement. Significant findings included: (1) retirement age has increased; (2...

Many clinical and epidemiological studies have shown that the polyunsaturated n-3 fatty acids EPA and DHA from fish and fish oils, provide cardiovascular protection, particularly in the setting of secondary prevention. n-3 Fatty acids beneficially influence a number of cardiometabolic risk factors including blood pressure, cardiac function, vascular reactivity and lipids, as well as having anti...

Why the brain is probably not a quantum computer

Based on a calculation of neural decoherence rates, we argue that that the degrees of freedom of the human brain that relate to cognitive processes should be thought of as a classical rather than quantum system, i.e., that there is nothing fundamentally wrong with the current classical approach to neural network simulations. We ®nd that the decoherence timescales ( 10ÿ13±10ÿ20 s) are typically ...

Why τ is Probably not Used to Guide Reaches Geoffrey

We suggest that τ may not be used to guide reaches. The reasons are: (1) targeted reaching is an intrinsically spatial task that requires information about length dimensioned properties (i.e. object distance, size, and/or velocity); (2) τ is time dimensioned and thus provides no spatial information. A τ variable can be constructed from perceived spatial variables and then used in a control dyna...
