Seemingly trivial things that intrigue you

I just find it fascinating that all the nutrition a large healthy animal requires is in one food source. When I think about it, it's incredible that a computer mobile phone... just requires electricity.rjsterry said:
No we evolved in an environment with varied food sources. 500 years is nothing in evolutionary terms. We've only partial adaptations to digest milk and we've been herding livestock for 15,000 years.focuszing723 said:
Sure, but it make you wonder if humans really require the selection of food we are pushed towards. It's only been what, the last 500-1000 years or less since our diets have been so varied. There was a lot of evolving before that, some people are intolerant to certain foods. Also, lions, tigers, wolves, birds of prey...rjsterry said:That's how they have evolved, in an environment where there's not much to eat beyond grass.

They can manage on grass but most horses that do any form of work eat lots of other stuff. Horses that are ridden regularly will generally be fed a variety of oats, pony nuts, sugar beet, carrots, apples plus supplements such as garlic granules on top of their hay or haylage when indoors. They'll each less when out on rich grass in spring althou then they quite often get brought in to avoid eating too much of it. Dry summers and then through winter they'll struggle to get the nutrition they need. 'Wild' ponies tend to be a bit more hardy and survive on grass along with other vegetation.focuszing723 said:
What interests me is how do Horses get away with just eating grass and hay?Lots of people have said:Eat a variety of food and don't forget your five a day, make sure the fruit/veg cover the colour of the rainbow...
Cows, sheep, goats, rabbits...Horses and Cows aren't exactly small either and look alright on a non varied diet. Look at race horses, bloody fit.0 -
What did Mr Ed eat?0

Incidentally, it's the becteria in cows' rumens that 'eat' the grass, cellulose and all, and the cows process what the bacteria 'excrete'. Reticulum, rumen, omasum and abomasum is the order of processing, IIRC.0

Teeth dictate the life span of a sheep. Pedigree tups get dental care!
Tutankhamun died of a tooth abscess. The Egyptians had very poor teeth because of the grit that ended up in the wheat in such dusty conditions.
Quite a varied diet from fruit to fish but they didn't live long.

One of the weird things I read about the other day is that there aren't 'enough' Iron Age skeletons based on the estimated population. There were either a lot of cremations or some other funerary process but Iron Age cemeteries are extremely rare.First.Aspect said:

Air plants, otherwise known as Tillandsia, are native plants to the southern United States, Mexico, Central and South America, and have the ability to thrive in the warm temperatures, despite neglect. With over 650 types of Tillandsia, these unique looking plants survive without soil OR water.
Air plants use their specialized leaves to obtain from the air the water and nutrients they need to survive. The roots of the air plant are simply used for attaching themselves to rocks, trees, shrubs and the ground. Most air plants grow with long, triangle shaped leaves and boast attractive funnel or tube-shaped flowers, offering beautiful architectural elements.
And air plants, they intrigue me as well compared to the magnitude of requirements we supposedly require.0 -
Why expensive bikes, especially TT bikes, have such ridiculously loud freewheels.

Not necessarily. It depends on the pawl design and the grease used.rick_chasey said:Why expensive bikes, especially TT bikes, have such ridiculously loud freewheels.

Thick grease will clog things up but be nice and quiet, purely as an example.The above may be fact, or fiction, I may be serious, I may be jesting.

I was passed by a pair of these when walking yesterday and thought the terrible racket was the solution to pedestrians not hearing bikes when they cross the road without looking. I always thought ut would be electric cars and natural selection that sorted that one.0 -
Sure but they’re getting louder - pro ones too. So loud they get picked up by the cameras on descents.pblakeney said:

Maybe you are used to listening to Shimano hubs. Have some teams moved away from them? Loud hubs are not new, and not slower.rick_chasey said:

I don't get it. It just sounds like somethings wrong with the bike. As for the low resistance oil viscosity, there must be a certain amount of energy lost in generating that noise.0
-
Yes, surely.
As the pawl springs into the backward facing tooth recess, that must create some resistance.
Perhaps the manufacturers figure that the only time the hub is going clackety clack is when you are free wheeling because when you are pedaling, it's silent. So it' pretty immaterial.

First time I noticed it was on my first sportive, from a bloke who for a while I couldn't shake off. I wanted to shake him off not because of the clackety-clack, but because he kept on doing an unpleasant grating/snorting thing with his nose, and he was fatter than me.0 -
