You can just as easily spend $1500 a person for a two week vacation in Europe and enjoy essentially all the same things as if you're paying 10x as much.
$5K daily incidental, are you kidding me?
Don't fly business class unless your business is paying or you're on a honeymoon or something.
Most on HN lack the background knowledge and training to usefully interpret a review article like this, let alone a journalistic simplification. Yes, I cite "thoughts from my own mind", a mind which has spent years researching this theme.
You're wondering why I don't cite any articles contradicting the claims of the review article? That's because this paper already cites many published peer-reviewed works, only to dismiss their findings. You'd know this if you actually read the paper and had the background and training to properly interpret it!
It's an interesting review. The main idea of the paper is that we shouldn't jump to conclusions so quickly when thinking that strenuous exercise can increase risk of short-term illness. The authors point out some logical and mechanistic fallacies of past studies.
I take issue with the interpretation that most people will have after reading - that strenuous exercise will not increase risk of getting sick. I know firsthand that this is not the case in truly elite athletes. But, for many people this may be true. It's important to be specific however, when discussing scientific matters, which is why I contributed my thoughts
"Each day participants ride, on average, about 100 miles and burn some 6,071 calories"
As a competitive, but still amateur cyclist I would do something in this ballpark almost every day. Hence 3000 - 5000 calories. And I'd often run for an hour or play soccer on top of this since I wasn't a pro.
I did spend a lot of hours on the bike, as serious athletes tend to do. Years of experience with myself and many other national caliber athletes tells me that we do in fact get sick from strenuous exercise, all the time.
Let me try to explain why there is no contradiction, and why the science here can't be relied upon across the board.
First, my anecdata pertain to athletes who are competitive on a national or regional level - Olympic Trials qualifiers, Cat 1 and pro cyclists, and similar. Science will confirm that these individuals have profoundly altered physiologies as compared to average "fit" people.
A problem with extending exercise physiology research to elite athletes is that most of the time, the scientists do not have elite test subjects available. There is a world of difference between the 4 hr marathoners they probably surveyed, or even 3hr Boston qualifiers, compared to the 2:20 and under marathoner I have in mind. There simply isn't much science published on these guys, because there aren't that many of them.
Many exercise physiology papers will say "well-trained subjects between the ages of 21 and 30", and the layman will think this means they studied top athletes. But then you look at the data and see that the average 5K run time for these people is something like 18 minutes, which is much slower than even the easy 20 mile pace for the subjects of my anecdata.
So maybe, the average marathon jogger is not more likely to fall ill after an effort. But talk to anyone who has run under 2:30 for men or under 3:00 for women and they will agree with what I have found
I suppose you are unlikely to see anyone here back me up since HackerNews isn't exactly an athletic demographic.
Fever, red eyes, overflowing mucus, extreme soreness and raw throat for days or over a week - are you trying to tell me that this isn't sick? Maybe that's your normal state, but I've seen hundreds of cases of amateur and professional athletes reduced to this shortly after performing national caliber efforts.
A serious endurance cyclist or swimmer will certainly go through 3000 kcal on a normal training day if not more.
I've burned an estimated 5000kcal daily on the bike for weeks. What's more is I know these numbers are very accurate as we train with power meters that record our energy expenditure with minimal error.
It's important to distinguish between serious athletes and average people who exercise. It's possible that truly competitive athletes - for instance, who run 120 miles a week to your 30 - will be much more likely to get ill from their efforts. It can take serious fitness - and a mentality acquired only by years of serious training - to push yourself to the extent that you fall ill, and maybe the recreational "athlete" described in this text can't reach that point.
There are perhaps a dozen times in my life when I was training with abnormally high intensity even for a very competitive endurance athlete and fell ill immediately afterward.
These range from 2 hr brutal races to 3-4 days of 5-7 hrs daily intense training or race efforts. I very rarely catch a cold, but it's more often than not after an effort that stands out to me as memorably difficult.
Any serious cyclist will agree with me. Even competitive high school athletes know that you are most likely to get sick right before taper.
This is an example of misinterpretation of scientific experiment, most likely by the journalists but possibly by the scientists themselves.
EDIT: I don't take issue with "immune response is heightened after exercise". I'm sure it is. I take issue with this quote: "But it is unlikely to have made you vulnerable to colds or other illnesses afterward, according to a myth-busting new review of the latest science about immunity and endurance exercise".
Bitcoin Private https://btcprivate.org/whitepaper.pdf will add privacy, we'll see how it goes. Also LiteCoin is introducing LitePay in a few days, which might change things.
NewYorkCoin https://www.wsj.com/articles/newyorkcoin-gains-traction-in-c... is actually used as currency in NYC, and is fast enough and has no transaction fees.
So we're at the early stages of things, but between Bitcoin Private, Litecoin, and NYCoin, I expect lots more people will be buying with cryptocurrencies over the course of 2018
