Higher aldosterone-renin ratios in older adults were linked to increased risk of atrial fibrillation and ischemic stroke, supporting the aldosterone pathway as a target for cardiovascular disease prevention.

I keep seeing studies
which find how Covid
damages the brain
and the lungs
and the heart,
and a new study finds
it raises the risk
of kidney disease too,
all of which is why
you will find me

Separated Bike Lanes Means Safer Streets, Study Says β€” Streetsblog USA Cities that build protected lanes for cyclists end up with safer roads for people on bikesΒ and people in cars and on foot, a new studyΒ of 12 large metropolises revealed Wednesday.

Never forget, a 13-year study found that protected bike-lanes led to a drastic decline in fatalities for all road users.

ALL ROAD USERS.

What about painted bike-lanes? No safety improvement at all.

For sharrows, it’s actually safer to NOT have them.

I regularly see people wondering how it's possible that there are so many musicians and writers and film makers and artists from a tiny nation like Iceland.

And the answer is really simple: State funding for art education and artists. I literally get a salary from the government to write books.

They won't start with banning birth control. First they'll lie about it. Then dictate who can prescribe it, use it, fund it, in what forms, and for how long. Suddenly, your doctor won't call you back. I know this is what they'll do because it's what they're doing to transgender healthcare right now.

I’m about as far left as you can get… but we do have problems with MAiD in Canada.

How do I know? It was β€œoffered” to me in lieu of care.

I’m disabled, I was alone, my conditions expensive.

Yes I was allowed to say β€œNo”, but no alternative care was offered.

That’s coercion.

Street transformation from car space to street willed with people including kids

Street transformation from car space to street willed with people including kids

It’s not just about what you remove (cars, noise, dirty air). It’s about what you add (people walking, a lot of bike parking, trees, outdoor dining, and room for kids to play safely). Amsterdam: 1986 and today.

Streets for people.

Busy arterial street filled with congested cars

Busy arterial street filled with congested cars

Bike-lanes don’t cause traffic congestion.

Car dependency, dumb land-use sprawl, too many (& bigger) cars being driven too much taking up too much space, highly subsidized driving costs, and not enough choices in how to get around, ALL cause traffic congestion.

Think about it. THAT’S common sense.

A portion of the StrΓΈget pedestrian street in Copenhagen that widens into a grand people-place.

One of the most successful pedestrian streets in the world, the StrΓΈget in Copenhagen, was filled with cars until a 2 year pedestrianization pilot project in 1962. The opposition argued β€œno cars means no business,” but the street has been a massive retail success, the city’s busiest shopping street.
