Yesterday marked 50 years since the first mobile phone call was made. A new survey reveals just how vital mobile phones are to people now. It found nearly 72-percent of people couldn't imagine going more than a weekend without their mobile phone, while nearly more than 23-percent believe they could last an hour at most. 41-percent are more willing to give up the gym, TV for 25-percent of millennials, or even sex for 22-percent of Gen Z responders than their mobile phones.
