Did it ever occur to you fat fucks designing the sensor that the reason these 65-70 year old men are maintaining many rice paddies is BECAUSE they walk them, instead of sitting on their ass and withering away.
This is one of those 'inventions' that sound like a good idea until you look outside your tiny ass little scope. It reminds me of the idiots who thought you could lock the Japs up in camps and feed them bleached white rice all the time and nothing else for nutrition instead of whole rice which is actually useful to the body unlike white rice
You may make it easier on them, but end up with them dying younger instead! Not my idea of a good trade off considering walking isn't exactly bad for you. America needs to try less to be lazy, you're killing yourselves to do it.
