It seem that just about ALL of new technology from many if not all areas has but one goal; to make something we currently do easier. What I mean by easier is, LESS PHYSICAL MOVEMENTS to complete a task or job. Everything has a remote or is "hands free." All of those movements,albeit small, when combined together are a large percentage of the exercise that we get during our daily routines. From robot vacuums cleaners to auto-cleaning kitty litter boxes we are being handed more time to sit on our expanding butts. At the same time we are moving less and less our food (calorie) consumption is remaining the same and in many cases increasing because many are using that extra sit time ...TO EAT ! ...Simple math will tell you that if you have more coming in than you have going out; you soon will be headed down a WIDE ROAD.
