There are plenty of people that will tell you that your school days are over.
There are plenty of people that will tell you that you are too old to learn.
There are plenty of people that will tell you that you can't teach old dogs new tricks.
But they are wrong.
Quite apart from Elizabeth Kirby who gained her PhD at 93, there is that of Kimani Maruge who held the Guiness World Record for being the oldest person to start primary school at 84. He knew that education was important and - most importantly - that you are never too old to learn.
Then, there is the case of Kenyan grandmother Priscilla Sitienei - who prefers to be called Gogo - who attends primary school with with six of her great-great-grandchildren.
She wanted to learn to read the bible and to inspire children to learn. Many older children no longer attend school and when confronted they say that they are 'too old'. Well, Gogo soon puts them right on that score. You are NEVER too old. And she is living proof.
The headmaster of her school calls her a blessing - which she undoubtedly is. And all of the pupils just love her.
She is an inspiration to us all.
She even has a sign on her dormitory at the school - it reads 'Welcome to Priscilla's Dormitory - Education has no age limit'. Well, we'd second that.
Elizabeth Kirby, Kimani Maruge and Priscilla Sitienei are all shining examples of Age No Limit!
