But resistance is proportional (roughly speaking) to the square of the speed, so half the time, but
4 times the effort.

Right answer, but not quite the right reason. As said on other posts in this thread, resistance
(wind) is proportial to the square of the speed, but the power needed to overcome that resistance
goes up as the cube of the speed.

So you go twice as fast = 2*2*2 = 8 times the effort, but for only half as long, so that's 4 times
the effort expended in total.

Ah, I must start shopping in Tesco's more often. Tesco's usually seem to have better range of
organic food than most supermarkets, on a vaguely related note.

Morissons? Never heard of them. We obviously don't get 'em round here.. :)

I know, but it's just one of those things that once you (well, me) start thinking about it, seems
to make more sense than not, which was the point the original poster was making. So while
weaning(!) myself off cheese might be difficult, I might as well just try to cut out all other
forms of milk if I can..

I suppose it's like driving: people do it because they just haven't thought about the alternatives,
but once you start thinking..

The Pure brand has no milk products in their sunflower or soya margarines. It seems to be available
at most supermarkets these days.

For a wide range of organic produce you need Waitrose. The fresh produce also lasts longer than it
takes to get home, which is a plus when compared to most supermarkets.

Try to find a balance between the "no carbs" and "carbs" days. The point is that carbohydrates that
are not burnt will be converted into fat. Carbs that you don't digest and/or do burn will therefore
never be converted into fat. That's why you lose weight quite easily.

<gentle ribbing> I always find it quite amusing how unaware we all are [1] of quite how diverse the
UK really is. We ain't got no Waitroses in this country! In fact, I think even in England they're
pretty much only a south-of-England thing, aren't they? :-( </gentle ribbing>

[1] ObCycling: I had a really fascinating conversation recently with a prominent English cycling
activist where he learned a heck of a lot about just how different the
political/legal/organisational makeup is in Scotland, and (partly to my surprise as I thought I
knew most of the gist of how things work darn sarf) I learned quite a lot that I didn't
previously know about English local - and regional - government as well!

We certainly don't have them here (Yorkshire). I've only ever seen them in London/Home Counties.

For me it conjures up images of the morning after one Chris Mason's 21st birthday, involving Chris
Mason, a can of Castlemaine and a box of cornflakes... No relation of Simon. I hope.

Hehe ;-) I was just teasing, Guy. Sorry if you took offence! I just thought it quite funny at the
idea of having to trudge 400 miles to find my nearest Waitrose.. :)

Ah, that would be telling.. :)

But it just goes to show, the way things work in Scotland is so different from the rest of the UK,
that pretty much we almost are a foreign country - and the worst bit is, that even most Scots don't
realise the extent of the differences(!), because (until recently) TV/radio news largely reported
government actions affecting England only (or E&W) as if they applied across the whole UK, and
unless you looked hard, you were none the wiser..

Not at all - I was enjoying the joke :)
