Does there have to be an advantage of snoring? Evolution hasn't made us perfect yet unfortunately.
Or maybe a disadvantage ?

From the statistics between all the different countries, I would extrapolate that there are more than 1000 per year but less than 10 000. I would imagine that around 25% to 35% of those happen where AK-47s are the most popular fire-arm so I could guess that conservativley at least 250 a year, more than falling coconuts.

Is that meant to be is there a specific disadvantage to snoring...?

If so, yes - usually it means you are getting less air into the lungs.

OK, small amounts of snoring, no probs, just like small amounts of alchohol, coffee etc. But large persistent levels => chronic fatigue and/or sleep apnoea.

Generally associated with an increased risk for diabetes, heart disease and high blood pressure. So there you go.

None, it is impossible to change a light bulb unless the lightbulb wants to change.

Seriously though, you will still be able to get these sort of incandecent light bulbs in the US, even after the ban.

Re: Ask a Scientist

Just watching the javelin on the telly and was wondering which, if any, is more beneficial, a headwind or a tailwind? Logically, I suppose, a headwind would help slightly with the flight, up to a certain extent, but would impede the run-up speed. The opposite argument would apply to a tailwind. This then raises the question, what speed tail/headwind?

A tail wind is the only option.

The aerodynamics of a javelin maybe streamlined, but it doesn't create "lift", so therefore a headwind will only create "drag".

Not so - it has an angle of attack to the airstream that is > 0, therefore it does create lift as well as drag.

Yeah, fair enough


but you'd hardly bolt two javelins to the outside of an engine and propeller and expect it to fly.


I guess you could say that the amount of lift generated by a javelin in flight isn't significant enough to gain a 'lift' advantage from a headwind.

The tailwind is still the correct answer.
