The word which describes webbing of digits is syndactly, so syndactile or something like that.

Hmmm, interesting, thanks. Though I think that syndactility might relate specifically to the fusing of structural tissue such as bone as opposed to the membranous webbing found on ducks, platypuses, otters etc?

There are anti-viral drugs but they are less general, more expensive and less effective than anti-biotics. They are most widely used against HIV, they can be made against colds and flu (the seasonal jabs that are offered every year) but aren't that effective and soon become useless as viruses change to different strains. If you get a different strain of cold or flu they aer useless anyway.

Many anti-biotics target a general weakness of bacteria, the cell wall and disrupt it in some way. You could look at anti-biotics as being like rust stimulators and so would affect many cars, an anti-viral would attack a Citroen Picasso C4 limited edition only for instance, which are good at hiding (inside your body cells as do viruses rather than outside cells in the body fluids like bacteria) and once they'd been found out would change the headlamp shape a little and come in 3 different exclusive colours so making the anti-viral useless.

Right.

So what about flies?

Haha

Yep, flies, flying in squares around lampshades during the day. Apart from guarding the lamp, it's a mystery to me.

Re: flies, they're in a holding pattern, or stack as it's known in ATC circles, prior to landing. You can observe the same thing at Heathrow. With planes, not flies.

Ah Bovingdon, is that what it's called.

I thought they flew in ellipses or ovals

And that doesn't really answer the question, does it?
