Over the last 100 years, humans' lifespan has only increased by ~5 years, if you lived to be a teenager. Think of all the 'productivity' we've had in the past 100 years, that's +5 years when you're already old and finished. Great. Can we do the math on how we've nearly blown ourselves up many times over, are destroying the environment, working 40+ hours/week and so on? Worth it for everyone to be 'productive' for a collective increase of 1 or 2 years within your lifetime, assuming we don't destroy the planet or blow ourselves up? You decide, keep your productivity if you wish, I'm going for a walk and enjoying my life :)
