Wordsmith, the discoverer of insulin was Sir Frederick Banting. There is a school named after him in Alliston Ont, where he was born, a half-hour drive from where I live near Barrie. For sufferers of diabetes, he's certainly earned the pedestal Wordsmith put him on -- and for the rest of us, he remains a source of nationalistic pride, inspiration and wisdom. From the link above:

It occurred to me when we were puffing up the hill and the train was speeding along away below that the engine with all its power could not go up that slushy, soft, snowy road as fast as we could. Power is useless unless directed in the proper channel. People have different powers and the big question in life must be-"Are we on the right road for travel?"

We will certainly not get far in our given time unless we have chosen the road that is fitted to our particular locomotive.

- Dr. F. G. Banting
