Do cellphones cause brain damage? The evidence is far from conclusive, but Alex Tabarrok writes:
[T]he fact of the matter is that cell phones do cause brain damage. Cell phones cause brain (and body) damage when people use them while driving. Cell phones distract, whether we measure in the lab or on the road, and they distract enough to make cell phone use not all that different from driving under the influence of alcohol (at the illegal level). In marked contrast to the studies on cell phones and brain cancer the studies on cell phones and driving are broadly consistent and suggestive of a small but significant increase in death (your own and that of others).

Men are worse at multi-tasking than women, for evolutionary reasons, but it’s certainly true that anyone who speaks on the phone while driving is doing something profoundly stupid. But leave that aside, here’s a thought I have: if speaking on the phone impairs a driver’s facilities in the same way that alcohol does, then would it also be the case that it has the same effect on other activities? Is multi-tasking, thus, as potentially hazardous in the short term as alcohol?
To take just one random activity as an example, would a man having sex while talking on the phone perform as poorly as a very drunk man? This is certainly an experiment worth carrying out, and I encourage you to go for it. In the interests of science.
