But that brain is also our downfall. Until our bipedal ancestors reached Homo sapiens they were doing just fine. But with Homo sapiens that brain has given us the ability to lose the amazing athleticism and instead sit on our backsides creating ever more successful ways to destroy the planet...

A lifespan which for almost all of the 4.5 million years of our bipedal evolution has been a maximum of 35 years. Even now we still start dying before we reach 30. Those two statements often shock people when I state them, but they are well known and understood. Lifespans like mine are due...

Agreed, BMI recommendations suit me but certainly not all. Across all, below 30 is ok. And saying over 30 is obese isn't true for many. For many it's just being a bit fat. .

I very much agree with that. I've always been suspicious of any medical consensus since they change so often. If I were to listen to many in here following the medics I'd think I was doing all manner of things wrong, Take dairy for example which so many say is some sort of evil. My whole...

I don't think that is necessarily true, and as I showed in this post, the Dutch are clearly defying that, as are the many German cyclists. What extended stays in the zero gravity of space has shown us is that the joints and bones need gravitational pressure and muscular pressure. Given non...

He knows that with the state the economy is in, the bankers will be needed from time to time to rescue it. If they refuse, he's sunk and so is his party. .

There's a huge flaw in this study: 70% of the Dutch cycle, 48% of them daily, the highest rates in the world. They are famously among the tallest of all European people. The longevity of Dutch males is two years higher than the EU average, the longevity of their females as long as the EU...

But truly cheap bikes don't have suspension. I've never owned a suspension bike, never would have done and never needed it, it has no place on bicycles. Look at the bikes they make and ride in India and Africa where much of all riding is off tarmacked roads, yet they never have suspension...

See This Link for ways you may be able to do it if it stands proud of the battery. .

Failure on all counts. The Lib Dems certainly aren't by popular consent. No distribution of policies since 1950 has kept our majority happy. It's why we are consistently near the bottom of the happiness league table with socialist Sweden always around the top. In truth to be fairly assessed...

Socialism is the centre of politics, governing for almost all the people by consent. Communism is the left and the far right of Conservatism is the right, both ultimately relying on police style militaristic compulsion to enforce their policies. Whether the Tories lose the next election and...

Consumer law has made it impossible for sellers to give truly useful advice on this. It's why the old term "waterproof" is no longer used for fear of the legal consequences, replaced now by "Water resistant", which guarantees nothing. .

If you mean Blair, No, that's expedient Labour which is a dead end that can never achieve it's goal of socialism. The same expediency that makes it no different from Conservatism, unprincipled winning regardless of the cost to so many. Saying one: "If at first one doesn't succeed, try, try...

That's an extreme comment. True Labour is consistently socialist, not Tory and not communist. If you want to know what that looks like, Sweden is an excellent fully functioning example. .

Given Starmer's record as the Crown Prosecutor for the country, yes. It set him up nicely with equally unscrupulous politicians to sail into politics. The Tories having destroyed Corbyn with their usual smear methods left an easy entry for Starmer, not just with Labour due to his parental...

Sinclair's two front or rear Zeta e-bike kits used D cells that were easily use replaceable. They were low powered though so didn't last long in the market. The trouble for most e-bike motors is the current is often too high for surface battery contacts. They need to be welded or at least...

The EV pollution from tyre and brake wear is grossly exaggerated by those who hate the change to EVs, especially since the motor braking to regenerate obviates most of the braking. EV brake pads seem to last for ever, much to the distress of the motor trade. They need far fewer replacement...

Agreed, and we have had a number of much cheaper friction drive kits over the years. But friction drive really only suits the light assistance market and that is small, hence most of them failing. True even without friction drive. US company Schwinn had a brave try in the light assistance...

None of them ever have had. It's only riders that need lots of gears, given electric motor torque, only two gears are needed to cover the legal and practical assist speed range of 4 to 15.5 mph. Also drive slip and resulting tyre wear is a potential problem with friction drive, especially in...

Ever since the Zap Kit of decades ago there have been large numbers of these addons of "new" friction drive kits. Even our own Sinclair came out with useless variants for either front or rear wheel drive. They all went the same way, into oblivion, due to their many disadvantages. .
