According to press reports, a survey conducted by HSBC shows that 30% of the UK’s 21.3 million over 50s have changed careers in their later working years and that 41% of those aged 60 to 70 have done so. While 21% of those who have changed their career did so as a result of being made redundant, 15% chose to "career shift" for a change of direction, and 11% because they were looking for a career that was less pressurized and demanding. 30% of 50+’s have changed careers in their later working years.
So - no! You are never too old.
