• So should all us oldies be ordering a pulse oximeter to have handy at home?

    I've ordered one. I thought I'd found one in the country (rather than shipping directly from China in ages) but the tracking numbers are a dead end so I'm not so sure. Good luck finding one.

  • My years as a smoker have fucked my blood oxygen levels, but yoga has lowered resting heart rate.

    Really?
    I smoked probably many more years than you.
    Started in 1975, gave up smoking in 2001, then took up vaping in 2014. Stopped that recently.
    I've had an spO2 meter for a while. My reading is generally 98% or 99%
