.The inventor of the world's first mobile phone says people need to "get a life" and stop using their cellphones so much.
In an interview with BBC Breakfast earlier this week Chicago engineer Martin Cooper said he barely spent any time on his phone.
"I would guess that I use my mobile phone less than 5 percent of my time."
Despite being the inventor of the original cellphone, Cooper told BBC Breakfast that people should put down their phones and live a little.
When asked by the host of the show what she should do if she spent more than five hours a day on her phone, Cooper was shocked by how long she spent on it.
"Do you really? Do you really spend five hours a day? Get a life," he chuckled.
In 1973 49-year-old Cooper invented the Motorola DynaTAC 8000X - the first wireless cellular device.
Cooper started working at the technology company Motorola in 1954 where he helped invent many products, including the first handheld police radio systems.
He graduated from the Illinois Institute of Technology in 1950 where he earned his master's in electrical engineering.
When inventing the cellphone Cooper said he envisioned how it would look before he thought about how it would work, CBC reported.
"Small enough to put in your pocket, big enough so that it could go between your ears and your mouth," he told CBC.
