Five-year-old Jack Postlewaite and his brother, Charlie, 10, are teeming with energy, as most kids are.
A particular passion of theirs is playing with their elaborate K’nex structures – taller than they are – that they have constructed in the foyer of the Lakeville home they share with their parents, Phil and Kathy.

The Postlewaites are participating in the Juvenile Diabetes Research Foundation’s Walk to Cure Diabetes at the Mall of America on Feb. 25.

From various pieces they have scored engineering feats of complexity and locomotion that would make famed inventor Rube Goldberg proud.
Add to these toys a trampoline and playground set and it seems these children are leading lives similar to others in Lakeville. But that is not the case.
Both Jack and Charlie have Type 1 diabetes, an autoimmune disease that requires them to wear insulin pumps and their parents to be available to test their blood sugar more than a dozen times every 24 hours. Unlike Type 2, which typically results from lifestyle choices, Type 1 has been linked to genetic and environmental factors, according to the Juvenile Diabetes Research Foundation.
Jack was first diagnosed in 2007 at barely 16 months; Charlie in 2010. In his short life, Jack has endured more than 18,000 finger pricks to test his blood sugar levels.
