In an age of smart phones, which I don't understand how to use,,, car so complicated under the hood , I can't find the alternator,,,,, rifles that look like they belong in Star Wars,,,,,, a da&n thermostat on my house heater that requires a college degree to operate, don't have one :( ,,,,,,,,,, these crap inventions make me long for the simplicity of a single blade of steel to shave with.
