A report by the Office for National Statistics is suggesting 70 could now become the start of old age.
Traditionally in the UK 65 has been a marker for the start of old age as this is when people used to to start drawing their state pension.
However, as more people live longer- the Office for National Statistics says old age could start at 70, causing much debate.
79-year-old Alice Liddell from Bath says she enjoys her rigorous routine and that it's not the age of the person that matters but the attitude.
76-year old Peggy Crome from Westward Ho won the World Championships Age Group Triathlon last year in Switzerland and in 2018 in Australia.
She also echoes Alice's belief that it is the attitude of the person that really counts.
