I had Delta once. Prior to it I would ride 30 miles on my bike like it was a breezy day. When I'd take breaks to vacation or whatever I could pick back up easily. A year after COVID, I'm struggling to hit 20 miles and I lose my progress easily. I'm not sure it's COVID related, but nothing else has changed in my life.

Lockdowns have also broken everyone’s regular exercise and healthy habits. On charts we all assign this to Covid, but lockdowns were an artificial, additional decision.

Oh no. I have created a new exercise habit thanks to lockdown. I got on the "get exercise equipment" train early. I'm MUCH healthier now thanks to lockdown; lost about 5 kg, can do 13 pull-ups, lift weights 5 days a week, etc.

This is interesting to contrast with the numerous studies mentioned here: https://www.statnews.com/2021/05/14/setting-the-record-strai...

This is how Science work old studies and new studies can come to contrast conclusion. Why? Because of time, better understanding, more data and many more facts. So yeah we will probably see more long covid problems in the next 2 years.

I just finished reading "Science Fictions" by Stuart Ritchie so I'm kinda super-sceptical now.

Like, was this study pre-registered? Or did they just mine the database until they found an association with p<0.05?

There certainly was some disruption in gyms as workout places, but I'd be cautious about systematic conclusions like "broken everyone's regular exercise and healthy habits" given observable factors like: * increased personal time for workouts for anyone working remotely (or forgoing employment entirely) * dramatically increased demand & prices for home exercise equipment * shifts to cooking at home March / April 2020…

Absolutely. Sales of bike exercise equipment (plus Peloton’s share price), and outdoor sports gear went parabolic in 2020 and remain at record highs. The idea that “lockdowns” inhibited exercise while in many countries exercising outdoors is laughable.

Not nitpicking, because I hope you're correct. That said, sales doesn't equal actual sustained usage.

Anecdotal: I run almost every day. Don't get excited, only 2 to 4 miles :) Early in the pandemic I saw plenty of new faces - often couples - out exercising. Some running, mostly walking. I don't see many of those faces any more.

This is actually the best reason to have people remain unvaccinated, and to not strictly mandate vaccines. I'm pro-vax (god, why do I have to say that?) but what's seriously pissed me off about this whole COVID thing is how quickly it became political. At the beginning there was a real sense of "we're in this together" but now you can be pretty certain of someones political affiliation if they choose not to wear a ma…

“Vaccines prevent you getting the worst of the illness”, on other words, a treatment…

I think this offhand and flippant, even if I personally believe what you're saying is true.

The largest issue with COVID was the over saturation of healthcare facilities, that's the only reason the UK locked down at all.

Oversaturated healthcare is a problem for people who have the worst effects of COVID and people who otherwise need beds, since their bed may be taken up by a person with COVID.

Vaccines lowering the spread of the virus may be true, not really going to argue that point, I'm more pointing out that vaccines do not halt the spread and thus a vaccine pass is a poor way of saying it won't spread.

Instead you just prevent the non-vaccinated from participating in society, when in reality we probably need people to remain unvaccinated due to underlying health conditions or to understand health complications that can arise through the vaccine and/or the virus when unmitigated.

I'm not claiming "anti-vax rights", though it might sound like that, it's just not very scientific to have no control population.

I hope wearing an Apple watch is not a risk factor for heart attacks? :-)

I can imagine there being a small positive correlation between wearing an Apple watch and having heart attacks, somewhat like the plane armor story from WWII ( https://en.wikipedia.org/wiki/Survivorship_bias#In_the_milit... ). Without the Apple watch monitoring your heart rate: you don't see the warning signs early enough and have a fatal heart attack, once. With the Apple watch: you get alerted earlier, get to hospi…

FWIW Apple watches are 100% not recommended as a way of telling if you're having a heart attack: https://support.apple.com/en-us/HT208931

They're also not testing for the more dangerous ventricular fibrillation.

Do you know if the immune response from the vaccine also causes that damage or not?

> Do you know if the immune response from the vaccine also causes that damage or not?

The vaccine appears to cause minor damage, but more likely from the spike protein than from the immune response. C.f. this article:

https://www.science.org/content/article/rare-cases-coronavir...

"She says she has preliminary evidence that vaccination can lead to microclots, although in most cases they go unnoticed and quickly disappear—an effect she and a colleague saw in their own blood and that of eight other healthy volunteers, which they sampled after their vaccinations."

The clotting issues would presumably come from the spike protein binding with your ACE2 receptors and downregulating them. Of course it's kind of moot, since empirically we know that getting the vaccine has a hugely positive expected value.

Omicron is not unstoppable. See mainland China. See Taiwan.

What has Taiwan done that NZ has not?

I'm not as familiar with Taiwan's measures, but the biggest difference between mainland China and New Zealand, in my view, is that China does mass testing.

When the outbreak began in Auckland last year, New Zealand was testing about 20k people a day. At that rate, it would take months just to test the population of Auckland.

In contrast, when a Chinese city has an outbreak, it will test the entire population of the affected neighborhood or city within days. That will be repeated every few days, until the public health authorities are confident that they have identified all of the clusters of infection.

What happened in New Zealand is that the public health authorities were never able to identify all of the infection clusters. They did a lot of contact tracing, but cases kept showing up that they couldn't trace back to previously identified cases. There was a low level of cryptic spread in the population that they never got a handle of. Mass testing would have addressed that problem, but New Zealand doesn't do it (and probably doesn't have the capacity in place to do it).

Both of these articles are about severe Covid-19, and study patients who were hospitalized . It is incorrect and irresponsible to extrapolate these two papers to the entire world.

Thank you.

I think this should be researched further. There are countries that are more or less unvaccinated and can serve as a control group. Without that you simply cannot answer the question.

Many of the "Covid-19 increases risk of XYZ" popular media articles lack baseline comparisons to other virus infections. (Disclaimer: Yes, we know Covid-19 isn't the flu, and it's more deadly.) My point is: how much does heart-disease risk increase post-Covid compared to say post-Influenza? Is it comparable or is the risk magnitudes larger than with other virus infections? This is an important benchmark, I understand…

That would significantly reduce the fear and who would want that?

Same goes in the other direction, the sniffles can also cause myocarditis.
