I'm one of the guys who made the website, and I thought a lot about these things too. You have good concerns. My group talked to doctors and epidemiologists before starting this project and we proceeded with these thoughts in mind.

If it were actually possible to go to your doctor or get tested for COVID-19, I would agree that this is not the best way to collect medical information. The reality is we don't have that fortune right now, and this is the best fallback we can propose.

If you have specific criticism that we can take to improve the form, I'd be happy to implement it.

We're biased towards action, not sitting on our hands.

Thank you, James.


Thank you for your effort, and apologies for being a bit hot headed about this.

Like I said I am sure you just have the best intentions. If you could add some kind of geo restriction/verification so that people are not able to enter at least ZIP codes outside the country they live that would probably be helpful already


Very good observation. I'll defer to our network of doctors and take their feedback on this. Thank you!


We might. There's some worry that e.g. showing a heat map of the data might be alarming, so we're trying to figure out where the balance is between transparency and cautiousness.


Yes, we get trend info. We're storing a cookie in your browser with a UUID that is associated to your temperature reading. If you submit temperatures for multiple people in your household, they all get that UUID, which we assume to be a household identifier.


Carson here, site developer. Thank you for the positive response so far, but also feel free to leave us constructive criticism. If you want to contribute to this effort, the GitHub is https://github.com/carsonbaker/takeyourtemp. We're working on it with frenetic energy.


Celsius would be good. It'd save me a manual conversion. And 98.6 is just a conversion from 37C anyway that ignored the rules of significant figures...


You might be on Firefox. I just fixed this!


Still broken on FF :(


Sorry! Try again.


Are you blocking reCaptcha?


You may be thinking of alpinism, where this is perhaps a little true. It's not true at all of rock climbing.


Your comment doesn't make sense. You can't choreograph the result of coin flip, but you can definitely rehearse a rock climbing sequence so that you always nail it. I can promise you there weren't thousands of moments on this climb where chossy rock, the sun, or chaos theory had anything to do with his success or failure.


It's also worth mentioning that 95% of the Nose can be free-climbed by just about anyone that really trains for it. It's hard, but it's not that hard. The Dawn Wall, in contrast, is basically off limits for your average free climber -- especially the middle pitches -- unless you're among the best of the very best.

You can check out the topos for each climb. This is the nose (http://www.supertopo.com/topos/yosemite/thenose.pdf [p15-16]), and you can see, with just a few exceptions, most of the pitches are graded 5.10 or easier.

This is the Dawn Wall (http://www.rockandice.com/dawn-wall-el-cap-yosemite-topo). It's much, much harder, particularly when you realize that the Yosemite Decimal System progresses like the Richter scale, in the sense that a step from 5.13a to 5.13b (an increase of 1 grade unit) is leaps and bounds harder to achieve than improving from, say, 5.8 to 5.9.


    It's much, much harder, particularly when you realize
    that the Yosemite Decimal System progresses like the 
    Richter scale, in the sense that a step from 5.13a to 
    5.13b (an increase of 1 grade unit) is leaps and bounds 
     harder to achieve than improving from, say, 5.8 to 5.9.
Although this was the myth I was taught (or what us precocious kids must have made ourselves believed, since obv. we were progressing so well/so poorly) as well as a teenager, it's false. The Richter scale goes up logarithmic base 10, so that 2 in magnitude is 10 times more than 1 in magnitude.

Climbing grades don't follow that, nor do they follow a linear pattern, (although they follow MORE closer to a linear pattern...). It's just that 5.10 is harder than 5.9; 5.13b is harder than 5.13a.

There's no mathematically exactitude over it. A 5.13b climb just "feels" harder than a 5.13a climb, and a consensus has been reached. YDS is after all, open ended. If it was logarithmic like the Richter scale, going from 5.13 to 5.14 (5.13a, b, c, d, then 5.14a) would be 100,000x more difficult, which obviously it is not. The original YDS from 5.0 to 5.9 were based on benchmark climbs (not in Yosemite, strangely enough).

Grades afterwards were added as things were getting a little crazy to be calling them, "5.9", so "5.10" was born. This also gives you the peculiarity where established 5.9 climbs are, "harder" than newer 5.10 climbs, and this repeats for 5.10d/5.11a; 5.11d/5.12a, as the scale kept going up.

Then you gotta remember that all the climbing areas in even just this country are geographically isolated, so a 5.9 in Eldorado Canyon is different than a 5.9 at Devil's Lake. Yosemite itself is known to be pretty stiff. Unless you're good at a particular style, then...

Anyways, it's a big mess, and it'll never be fixed. What Ondra is doing is pretty hard. Let's remember he's only 23.


It's a log scale, just not necessarily log10.

It's like lots of things in sport, actually. Imagine the progression from running a 6 minute mile to a 5 minute mile to a 4 minute mile. Now go to a 3:55 from there. It's a much smaller notch than 6:00 to 5:00, but will take you ten years of training.

So sure, you can consider it just adding more weight to the bar in a linear fashion. It still a lot harder to lift each individual pound as the weight increases.


Actually, I don't consider it like adding weight, since climbing grade difficulty isn't calculated in a way that would be so simple.

There's no objective way climbs are organized in difficulty except by subjective feeling. Holds may be (say) smaller, and/or farther apart, but the difficulty can only be sussed out in a general sense - there's far too many things to take into consideration.

Compounding all this is that a climb could be more/less difficult because of a climber's body type (tall/short climbers excel at different climbs)

So you're left with a consensus, which is living and breathing, not a calculation.


I've always thought of it in the way that if you went to an area like Yosemite or Font (bouldering) - then for every 100 people messing about, then 10 of them would be able to climb (5.12, Font 7a+) and 1 of them would be climbing (5.13, Font 8a).

Those difficulty conversion are possibly way way off and this areas may attract particularly good climbers ... but my point is the scale is logarithmic in the sense of how many people can achieve each tick level.


At least in bouldering, John Gill proposed the, "B" scale, which measured basically how many people were able to top the problem. So if you established a climb, it gets a grade of, "B1", until another person gets sends it "B2". This scale basically favors the hardest problems being the most important, and adjusts the grade of the climbs, as the "sport" progresses.

Gill was a Math professor, so this is somewhat interesting to the discussion. He famously thought of boulders as, "problems", of course.


Yeah, 5.10a -> 5.10b is about the same step up as 5.7 -> 5.8 and the Yosemite Decimal System was indeed developed somewhere other than Yosemite: Tahquitz/Suicide in Southern CA [1] (where many of the golden age climbers and stonemasters honed their skills)

[1]: https://en.m.wikipedia.org/wiki/Tahquitz_Peak


My suggestion is that it's not. I would be very curious on how one can empirically prove this.


Since the grades are subjective, and largely determined by the first ascentionists, (although through consensus sometimes re-graded) this is not possible. My subjective take on it, up to 5.11+, can't speak for anything beyond that, is that a bump in a grade, any grade is about the same increase in difficulty. My climbing has mostly been in Joshua Tree, Idyllwild, Smith Rocks and a bit in the valley.


Don't forget about the time honored tradition of sandbagging! You alluded to it a bit with the 5.11d/5.12a comment.

Wow, I haven't even seen a 14b on an actual gym wall; I have absolutely no idea of how hard it is compared to a 11-12


I guess there's no point adding >14 on a gym wall as only a handful of individuals on the whole world could climb it.


It's just very different, to the point where you can't even compare the two climbers with the same ruler. Honnold's biggest achievements are notable because of the risk he takes while soloing. Ondra -- although he tackled some bold climbing on the Dawn Wall -- didn't stick his neck out there in nearly the same way, but instead performed a sustained exhibition of incredible athleticism.

They're both the best at what they do, but they do different things, and I don't think either of them could do what the other does.
