Reply to comment by No-Sock7425 in Lung cancer patients with moderate to severe depression at diagnosis are 2 to 3 times more likely to have inflammation levels that predict poor survival rates, a new study found. (n=186) by geoff199

That's a good question. It is of course very natural to be sad about a diagnosis of lung cancer. That's not the same as depression. Severe depression is not normal, even if it is somewhat common -- about one-third of patients do have that. The important thing is that the depression can be treated and patients can be helped.

You can’t necessarily make that comparison since you’re dealing with different groups of people. This study indicates the Yamnaya- a pastoralist people of the Pontic-Caspian steppe- were riding horses several hundred years before the great pyramid was built in Egypt. It’s also important to note that horse domestication =/= horse riding. Even this article notes evidence of horse domestication that predates this. Meat, milk, pack animals, chariots, these things all likely predate horse riding given that wild horses didn’t have backs strong enough for it. Horse riding likely would’ve come along after generations of domestic horse breeding for those purposes.

Reply to comment by Sir_Squirly in Study reveals that although private automobiles continue to be the dominant travel mode in American cities, the share of car trips has slightly and steadily decreased since its peak in 2001. In contrast, the share of transit, non-motorized, and taxicab trips has steadily increased by giuliomagnifico

A car for someone who is poor is like a poverty tax. That’s why it’s so terrible we’ve designed cities around car ownership. It really hurts the working poor.

The average annual cost of new vehicle ownership is almost $10 000 a year. A small sedan is the cheapest at $7000 a year.

Yes, this average cost takes into account loan interest, depreciation, fuel, insurance, maintenance and fees.

If people knew how damn expensive car ownership was upfront, we’d probably have less cars and more public transit.

The reality is that many cities are seeing more cars on the road due to ride share services. Ride share doesn't work if there's not some capacity existing to offer service relatively quickly when a user opens the app, so now there are lots of cars driving around looking for their next ride.

Absolutely valid.

In my case the service is there, hence why it is legitimate to change a public transit fee on the yearly plating fee. Buddy with a plate registered in the sticks has no public transit charge. Other fellow in suburbia of Montréal pays lass plating fees than me in the city since there is less public transit.

As long as we do it humanely I don't see an issue. We see a ton of piggybacking throughout the animal kingdom from parasites to more complex symbiotic relationships. And then from another perspective, the animal world is insanely cruel to each other. It's just the circle of life. Domesticated horses can/do live happy, full lives. I'm completely against any inhumane treatment of animals we use for utility or otherwise, but utilizing the utility of horses, mules, camels, ect doesn't have to be inherently cruel, especially in comparison to how the animal kingdom interacts with itself.
