Maybe people with thinning in brain region associate with memory overestimate the amount of time sitting because they can’t recall as accurately what they were doing in between sitting sessions...
Incredibly stupid experiment. As someone who is red-green color weak, just as 10% of the male population is, I feel insulted by the implication of this article and the obvious glossing over the fact that not all humans see green/red very strongly. This is lazy science, seriously asking people to differentiate between images of apes that want to mate? It made no sense, you basically proved that some people are colorblind... ok. Did you plan and write this over a weekend? Why did you even bother?
Good point bringing up over/underflow, I didn't think much about Nan or infinity, but I did consider potential over/underflows. I originally built an overflow/underflow checker(on the github project), but then re-evaluated it and figured it wasn't really necessary since the default action for number types that overflow/underflow in swift is to throw an error runtime. The person asking the question mentioned another series of operators that exist &+, &-, &*,etc that allow for overflow/underflow to occur on number types in swift.. without the error throwing, which is not the default.
I use the dot property conversion, not the overloading in general use. I also have such reservations about using overloading for casting in production. What I do use, is the series of extensions for single letter dot property conversions, the extensions without the protocol extending, that I also used in Swift 1.2. Sorry if that was unclear...
