Thing Possibly To Do Today: bike.

 Yes, you may say, biking is healthy and green and all that, but I don't have a bike. 

But that's all right, because you don't necessarily need one.

In Britain, on your bike! means go away, you don't fool me. On the other hand, to get on your bike means to set out with a determined purpose, probably to find a job.

In Australia and New Zealand, on the other hand, to get off your bike is to lose all self-control,

And in Scotland to bike means to swarm (a bike is a bees' nest).

So there we are. Several kinds of biking, and some of them without even breaking sweat.

On the whole, though, the pedalling kind is probably the easiest.

(Except that I don't have a bike...)

Thing Possibly To Do Today: bike. The word bicycle comes from the Latin bis, which means twice, and the Greek kuklos, which means wheel. The origin of the Scots word no one knows.
