Anna Bailey had lived a busy life. An IT professional, cat breeder and national cat show judge, she was also prone to bouts of depression. But approaching her 50th birthday, she ruled out self-pity and decided that it was time to get back into shape.

A trip to a local gym seemed unremarkable enough, until she tried out the rowing machine. She was quite good at it - so good in fact, that within a year she would be travelling overseas representing her country in competitive indoor rowing competitions. Within two years she was age-group World Champion.
