More importantly, precisely which medical tests require an accelerometer? Not being the sort of malingerer who spends a lot of time undergoing medical testing, I may have missed them but I'm pretty sure that no doctor has ever attempted to measure my acceleration. I know that older people often claim that time seems to pass more quickly. Perhaps time passing more quickly actually manifests as a measurable reduction in their acceleration and acceleration tests are a geriatric specialisation that I can look forward to as I get older. Perhaps the more senior SlashDot followers would care to comment on the efficacy of acceleration testing?
Never trust an operating system.
