Where I'm from (Ukraine) RSI is pretty much unheard of, and I only learned about it when I moved to the US (when I was 21). Interestingly not long after learning about it I've started experiencing pain in my wrists and started to get really worried about getting an RSI. One of my coworkers recommended Kinesis Advantage keyboard, so I bought it off ebay and started using it and the pain disappeared. Interestingly I've seen this keyboard quite a lot, off top of my head I think something like 5% of engineers were using it.

I'm not saying that RSI doesn't exist, but I'm now positive that in my case all those RSI-like symptoms were all in my head -- some kind of a nocebo (an anti-placebo) effect. When I was 27 I had to do an MRI of my hand for an unrelated reason (boxing injury), so naturally I asked them to do an MRI of my wrist since they'll be immobilizing my hand anyway [1]. So either my wrist was healed in those 6 years, or it was fine all along -- can't tell because I didn't have a "before" picture. Just in case, I explicitly double checked with another doctor if he was sure about my wrist and he said that my MRI could be used as a textbook example of a healthy wrist joint.

I am now wondering if all those "mental-health awareness" things could have an adverse effect. I wonder how many hypochondriacs self-suggested themselves an OCD or an ADHD, and while marinating in those thoughts they somehow turned those thoughts into an actual condition (self-fulfilling prophecy?). Like ... you guys already have tidy people joking about having an OCD, and people who like to wash hands are joking about being a germaphobs.

edit: I think I've seen an article "willpower is limited only if you believe so" posted somewhere here on HN, but I can't find it now. Anyway here's another link: [3], and here's the Stanford study they cite [4]. This can be another example of people self-suggesting themselves a handicap.

[1] There are a lot of posts on HN talking about healthcare costs in the US, so I'll share my anecdote too. I did an MRI in Ukraine and the whole thing was like $80: $50 for the hand and extra $30 for the wrist. The machine was 1.5 Tesla one, but there are other clinics that have 3 Tesla machines too (a little bit more expensive). Scheduling an appointment was done by a phone a couple of days in advance and didn't require any doctor referral. There are many small private clinics offering imaging services (MRI/CT/Ultrasound/...), and all of them are very easy to Google and all of the prices are available online, for example: [2]. After the procedure they give you a CD with the info, a print-out on some largish transparent plastic, and their staff doctor's conclusion. You usually take those results to your specialist doctor of choice.

[2] For example: https://translate.google.com/translate?sl=auto&tl=en&u=https... all prices in UAH, to get rough USD estimate divide those numbers by 25 (or 26.75 to get exact number as of 2019-03-13 if you're OCD).
