Yes, but they bend backwards and are hidden under their feathered knickers.

Don't their feathered knickers slow them down when they fly?

If you want a pool ball to swerve to the left, you hit it on the left. If you want a soccer ball to swerve to the left, you kick it on the right. Can anyone explain this?

(Please show your sources, references, academic studies, working, crossing out, etc)

common sense tells me that one is overly dense

and one possibly over-inflated

I'm not going to explain it fully,  but in sports that use a prolate spheroid you you may get an intuitive understanding of what's going on.

But first let's look at cricket just to establish some terminology. A bowler can get a ball to move in various ways:

Swing is conventionally caused by the way the seam interacts with the air. Not relevant to your question.

Seam is natural deviation when the seam hits the pitch. Again this is not relevant.

Spin is caused by the rotation of the ball when it hits the pitch or playing surface.

Drift or swerve is caused by the rotation of the ball moving through air. The Magnus Effect.

The snooker ball, IMO, is spinning or interacting with felt. The soccer ball is swerving or undergoing the Magnus Effect.

You can see the difference in Aussie Rules or Rugby League (it's not used so much in Rugby Union).

A right footed "banana kick" will curve to the right in the air. But, will curve to the left along the ground.

Why is it that scientists are still unable to definitively explain why animals (including us) yawn?

Because, while they're already fully aware of the reason for why we yawn in response to a yawn -- or even at the suggestion of one (btw, i yawned reading that!) -- they still can't offer even one reasonable scintilla of explanation for why we even yawn in the first place?

I understood yawning to be a way of getting oxygen into the body faster than by normal breathing ...... a way of waking us up a little.

What do you think is in the back of his van? He only has five letters to post!  Everyone with a Greendale postcode is off their tìts thanks to Pusher Pat.

Actually this is quite interesting ...

The plate is currently available to buy at the price of £155,000, and even though Pat is back in business with his new animated series, he will have to work a lot of overtime to buy it!

American football sprung from rugby. The rugby balls oval shape comes from using a pigs bladder. Oink :-) hence toss the old pig skin.

Either birds evolved from dinosaurs, or the dinosaurs were wiped out by an asteroid. You can't have it both ways, can you?

oh yes you can! if only the big, beefy dinos were wacked, it'd leave a lot of room (and breathing space) for the little guys to figure out, "just a few more feathers, and i could achieve rudimentary lift!"
