  • Today is your day
    In early 2023, arriving back from New Year holidays, I realised that I had really neglected my own health. On recommendation from Jessica Sachs and Marc Backes, I downloaded Noom, dusted off my Oura Ring and set off to look after myself a bit more. - Source: dev.to / over 1 year ago
  • My Company Just Made Me 2 Years Younger
    According to my Oura ring, my cardiovascular age dropped from +1 year to -1 year (based on my chronological age) last week. That’s right—my heart just got two years younger in three weeks! Nothing else changed in my lifestyle, besides starting that cardio challenge. Alongside this, my cardio capacity and sleep quality have also improved, also as measured by Oura. - Source: dev.to / about 2 years ago
