So she broke her hip. And I must say, I wonder about the risk of
breaking bones among the elderly. One of my cycling friends was told
she has enough osteoporosis (or perhaps a precursor condition) to
justify weight training and other measures. You'd never think this
by looking at her or talking to her, but she goes to a gym a few
times per week and lifts heavy things, because it's good for her bones.

My reference was to the famous study showing fewer lower
limb fractures among cyclists wearing helmets. What are you,
some sort of science denier?



A large number of "papers" that have been cited as science are by
post-grads and the largest pile of garbage possible. Going through the
various science magazines which is supposed to keep you up to date is
enough to turn your stomach. I especially like the Dark Matter "we
found it" and the exact same experiment conducted at another location
reveals nothing at all. One would think that the original
experimenters would look for secondary means of noise causing false
signals but instead they say "uh huh, we really did find it."


I laughed through a recent Science News at a report that after the utter
failure of 'xenon1t' to find anything at all, a new antimatter theory
postulating a new imagined particle called axion [1] will require a new
larger more expensive detector installation.


I confess to extreme disinterest.

When I was in college, I had quite a bit of curiosity about astronomy,
cosmogony, relativity and particle physics. I still read a little bit
about them. But very little.

ISTM that we've settled that the Big Bang gave rise to the universe.
(But as one Bloom County character said, "But what caused the Big
Bang?") And we've settled on the structure of the atom, down to most of
the sub-atomic particles that have any potential relevance. Relativity
has been confirmed to a very reasonable degree. So I'm comfortable
checking those off as Done.

At this point, what practical benefits are likely from understanding
another smaller layer of subatomic particles, or the math of black
holes, or 11 dimensional string theory, or whatever's out there in the
Oort Cloud? What are we going to do with that stuff?

I think it's time to direct our attention back toward practicalities.
Take eyeglass mirrors, for instance...

The article says it happened last month. December. She is supposedly
from Michigan. Or has one of her mansions in Michigan. Or her Amway
husband's mansion. I'm pretty sure its cold in Michigan in December.
So bicycling accidents are kind of rare in December when its freezing
cold. I live a couple hundred miles south of Michigan and there is NO
bicycling in December in my state. Was she vacationing in the Bahamas
or Caribbean when this accident occurred? Boss on vacation in the
tropics while the poor education teacher peons have to work?


Another Socialist comments. "Someone else has something and I want it."


Hey, you can join Amway too, and "live the dream".

So X-rays lie. Interesting.

If you say so.

Also interesting that you think that calcium
more suited to adults isn't available in more than sufficient quantities
in other foods less likely to cause digestive problems.

Oh, you have a M.I.L.K intolerance. I'm sure Big Pharma has a product for
every imagined illness that you can think of.

Lol, that's how science roles. Are you only just realising.
You can't be a outstanding scientist if you don't pubish and publish
early these days, Take a good seat and stand by for the next brain fart.

Relevance for many of us here - ISTR a study showing bone density loss
in endurance cyclists; I think they conjectured something about calcium
depletion due to electrolyte loss. Dunno if it was corroborated later.

Oh, here's a reference:
https://www.trainingpeaks.com/blog/w...an-improve-it/

Here's another, more scholarly reference:
https://bmjopensem.bmj.com/content/4/1/e000449

I have a (male) colleague, 60ish, who has some severe chronic back
problems attributed to osteoporosis. His experience certainly scares
the hell out of me. Definitely not a picnic, and worth efforts to avoid.

It's actually related to the lack of weight-bearing exercise, which stimulates calcium uptake and strengthens bone. Many 'endurance cyclists' do little or no weight bearing or impact exercise. Couple that with the idea that many also don't replenish electrolytes appropriately, and you get a 50 year old in great cardiovascular health that can't touch his toes or stand up straight. There's a ton of info available that correlates weight bearing exercise with calcium uptake.

Yes, interesting. Then there was the Scandinavian study that was the
first (AFAIK) to demonstrate the endurance athletes had a far higher
incidence of Atrial Fibrillation. It all gets a bit scary.

The Training Peaks article talks about applying serious loads, including
what sounds like shock loads ("Plyometrics"). But I can think of two
friends who were not only avid, fairly fast cyclists, but also diligent
weighlifters. Both were very muscular.

The one (who was my boss for a while, roughly 25 years ago) told me many
times that he wanted to stay as strong as possible so he didn't end up
crippled. I had a phone conversation with him maybe 5 years ago and
asked how he was doing. He said he had terrible arthritis in multiple
joints, and it really restricted his activity. The other guy, long one
of my favorite riding and hiking friends, can no longer do hikes because
his knees are so bad, and also complains about his shoulder joints, his
bicep aches, etc. etc.

I think it was Grant Petersen who described his ideas about good
exercise and bad exercise. IIRC, he opined that anything too long or too
strenuous done too regularly was likely to be bad for you in the long
run. And then there was Greg LeMond, who once said that for cycling, you
want an upper body like a 12-year-old girl.

Maybe we should all lift some moderately heavy weights, do a moderate
number of jumping jacks (or whatever) and ride, but not too fast?

And I wonder - is there data showing exactly which physical activity
does the best at providing a long and healthy life? I'd have guessed
bicycling, but maybe only if done not too hard.

No cycling in December? It's around zero F here with 8" of
fresh snow and yet there's cycling in Wisconsin.

There is very little cycling in Wisconsin right now. Just like with all the northern half of the USA. Cycling goes down to almost zero in the cold, snowy months. I am sure you have a bike rack in front of your store. And in the summer months there are a few bikes parked in it. How many bikes are in the rack today? And the only people who cycle in Wisconsin in the winter are the truly dedicated who cycle no matter what. Not the ones who cycle for fun. I doubt old Betsy is a serious dedicated cycle at all costs person.

WTF is this marxist class struggle on a bicycle tech conference?

Andre Jute
Out in Oz we called people like Russell "Pommie Wreckers"


Well Russell is convinced that with Socialism we could be as well off as Venezuela.


Only a fool such as yourself believes Venezuela practices socialism. Most of the so called socialist countries are not socialist. They are dictatorships. Venezuela, Russia/Soviet Union, North Korea and others are/were all dictatorships. One guy takes power through the military and steals everything. Probably China is the only somewhat successful true socialist country.. They had/have plenty of dictatorship too. But they did/do more or less practice socialism. They improved the lives of the vast majority of their citizens (one Billion). They tried/trying to distribute the benefits to everyone. In China today you have maybe half the one billion who are middle class. Whatever is considered middle class in China. And 50 million rich. And 450 million poor/peasant. Compared to capitalism where you would have 50 million rich, 100 million middle class, and 850 million poor/peasant. So socialism has worked in China.

It's global warming here -- the mildest January I can recall in the last 35 years. No rain gear today and lots of riders. I wore a wool long sleeve jersey and light jacket to work this morning and light long finger gloves. During the first weeks of January, I'm almost always in full winter gear coping with rain, ice and periodic snow. It's still raining a fair amount, but that's it so far.
