Do you have such problems in your life?
CAN NOT find the switch when you back home to turn on the light in the dark
DO NOT want to get up to turn off the light when you are sleepy
DO NOT want to turn on the light in the dark when you get off at midnight
DO NOT want to get up to pull the curtain when you are in the couch
DO NOT want to get off the bed to open the air conditioner in the cold winter
The elderly have difficulty in standing up due to aging
