Coronation Street viewers were left in disbelief over Ken Barlow star Bill Roache's age on Monday's Lorraine as they refused to believe he is 91 thanks to his youthful looks.The actor, who was born in 1932 and has been on the cobbles since Corrie's first-ever episode in 1960, appeared on the ITV chat show to reveal he had gone skydiving for the first time in his life and he shared his experience with fans at home. In the pre-recorded feature, it showed a delighted Bill skydiving with an instructor before releasing the parachute and landing in a field.
