comment Are there any known cases of falling elevators?
As someone who worked in the elevator industry, I can tell you that elevators are fitted with several independent safety systems which are subject to inspection after manufacturing, procurement, assembly and installation. Some of these devices, such as speed governors, are purely mechanically actuated, simple and reliable (hard to calibrate though). Most accidents are caused by neglecting safety precautions during installation and maintenance. Free fall of the cabin for a few stories in case of emergency is not unusual especially for fast elevators, as most safety devices are speed-dependent.

comment Do facial expressions cause wrinkles?
@Oliver_C: I have a copy of the paper in front of me, and this is what it has to say: ... suggesting that those who show more wrinkles with expression at any given age will tend to show more persistent wrinkles at a later age. Later on, they give an example with smiling temporary pattern that eventually evolves into permanent one, and suggest treatment of not only persistent, but temporary wrinkles when making facial expressions, so it looks that it applies to any type of temporary wrinkles. Contact me if you'd like to study the article itself and include more information in your answer.

comment Is hair colour correlated with intelligence?
@Tom77: Of course, the core question is a duplicate, but the way the way it is to be answered is definitely not. As I mentioned, I'm not looking for some vague lumped statistics which compare apples to oranges, but actual results from conducted studies.

comment Is hair colour correlated with intelligence?
@vartec: I honestly can't see how ethnicity plays any role in this, unless you are trying to assert that certain ethnic groups perform worse generally than others, all else being equal. Besides, not every country in the world is as ethnically diverse as the US.

comment Does using moisturizer regularly have long-term positive effects? And is it better to start sooner?
Disclaimer: this is very far from my area of expertise, but I nevertheless tried to analyze and summarize the article in question.
