This is cool but I can't say I agree with actually doing it. Just because you can do something doesn't mean you should, particularly in matters of health. If you don't have the requisite experience and knowledge and training, it seems risky to go about something like this on your own.
No more risky than changing your car's brake fluid (risk of death if you do it wrong). A lot of services that we have been conditioned into thinking need to be administered by specialized professionals with N years of expensive schooling, can probably be DYI'ed with access to the right equipment / tools.
I expect in the future we'll be hearing a lot of this kind of vague alarmist sentiment coming from well paid practitioners in industries so far untouched by technological competition & outsourcing.
