Living to be 100 years of age seems unrealistic to many who are happy just to wake up every day.For Doris Corbin, however, it was something that was expected having seen her father and aunt both reach triple digits.William Heyliger lived to 102, while Alice Heyliger went even further, reaching 105.Mrs Corbin turns 101 tomorrow, but insists she doesn't even worry about age anymore with longevity running in her blood.“My father lived until he was 102 and my aunt went to 105 so you can say that it runs in our blood to get this far in age,” she said with a smile. “I certainly don't feel my age and am still enjoying life.”The centurion was born and raised on North Shore, Pembroke, and devoted 41 years of her life as a primary schoolteacher at Central Primary School, now Victor Scott Primary School.An organist of St Paul's, she received in 1983 the Certificate and Badge of Honour by the Queen for her service as a choral director, teacher and an official of the Girl Guide Movement.Mrs Corbin conducted the choir at Bermuda's National Stadium for the Queen's Silver Jubilee, 40 years later, in 1977, and recalled the Queen personally wishing her a happy birthday last year as she reached triple digits via card.Reflecting on past memories, the Member of the Order of the British Empire (MBE) vividly remembers receiving the honour at Buckingham Palace.“It was like yesterday, although it was many years ago,” she said. “The Queen is such a nice lady, she invited me into Buckingham Palace and gave me the medal of honour.“To say that it was an honour to be in Her Majesty's presence is putting it mildly, and I was quite confused as to how I was supposed to thank her.“The was a great moment in my life, along with helping others in my travels across Europe with the Girl Guides.“The Queen even remembered my birthday last year, which was very surprising.”Premier, Paula Cox recently labelled Mrs Corbin “a national treasure” in expressing congratulations, best wishes and gratitude on behalf of the government and people of Bermuda.Though she comes from a long-lived family, Mrs Corbin attributes her longevity to staying fit, stretching every morning before getting out of bed to enjoy the day.“I keep up my exercises,” she said. “Before I get out of bed, I do my stretches to get me ready for the day. It is very important to me and has become part of my everyday life.Since her husband Clarence passed away in 2010, she now lives with her son Canterbury, while her other son, George, lives in New York and makes regular visits to his mother.“I am very fortunate to live to this age, and I enjoy every day I am here.”
