I recently bought a spray-on deodorant. When I got it home I realised it was intended for women but, not wanting to waste money, I used it anyway. Nothing untoward happened and I received no strange looks from colleagues or friends. So what are the differences between deodorants meant for men and those that are meant for women? How might using the "correct" deodorant for your sex work better than using one meant for the opposite sex, and what are the pitfalls of applying a deodorant intended for the opposite sex?Alan Ainscroft, Leeds, West Yorkshire, UK

Partial recall

Sometimes during a quiz, we know that we know the answer to a question even though we can't bring it immediately to mind. How?Here's an example. Question one: what is the capital of France? I immediately know that the answer is Paris. Question two: what is the capital of Uzbekistan? I immediately know that I do not know the answer. Question three: what is the capital of Portugal? I know that I have the answer in my brain, but I can't quite remember it. Then, as the answer is read out, I agree that it is Lisbon.In some cases, for hours afterwards I know that I know the answer to something but can't recall it. So how is it that I can know that I know the answer to a question but, despite that, still cannot retrieve that piece of information?Alan Rae, London, UK(Image: klsa12, stock.xchng)

Shampoo pooh-pooh

I have just read the label on my shampoo bottle. The list of ingredients is mind-boggling. How on earth did anyone come up with such a complex concoction and what exactly are chemicals such as sodium diethylene-triamine pentamethylene phosphonate and hydroxyisohexyl 3-cyclohexene carboxaldehyde doing to my hair?

Wound licking I know that some animals treat simple injuries by licking them. Are there any animals that, like humans, treat each other's injuries, and do any animals have more sophisticated forms of "medical treatment"?David Taub, Karlstad, Sweden

Eaves droppings While repairing a gutter on my roof I spotted a small patch of what looked like tiny eggs under the brick eaves (see photo, left). The patch was no larger than 2 centimetres by 1 centimetre. Each egg was the size of a pinhead. What are they, what creature is responsible and are they common in the UK?Steve Roderick, Bishops Itchington, Warwickshire, UK

A matter of timing

When I use a stopwatch to time events, I know that the accuracy of the result is subject to my ability to stop the watch at the correct instant. I am also aware that I must often be at least a few hundredths of a second out.Before the advent of electronic timing, world records such as those in athletics or swimming were measured with manual stopwatches. How accurate were these timings? Was more than one watch used and how did officials ensure they were as accurate as possible?Alan Mann, Truro, Cornwall, UK(Image: Daino_16, stock.xchng)

Why would people's hair stand on end when out for a walk? Walking along the breakwater at Berwick-upon-Tweed in north-east England recently, my granddaughter and her mother noticed their hair was standing on end (see photo, above left). It started to rain soon afterwards, but there was no thunder or lightning that day. What was happening?Richard Turner, Harrogate, North Yorkshire, UK

Fungal goodness We are constantly being exhorted to eat five servings of fruit or vegetables a day, cut down on red meat, eat more fish and so on. But very few mention that other kingdom of gastronomic delights, fungi. What nutritional value does your average edible fungus have?Rachel Cave, Galway, Ireland(Image: stock.xchng, LarryLens)
