My dad could fix anything too. He was a WWII vet. He never complained about any illness.
Even when he was dying of pulmonary fibrosis he never complained. I remember I was about to drive back to the airport when he was weazing - gasping for breath even with oxygen. I asked him if he wanted a hands-on healing. That's what I do for a living when I'm not writing. I was flabbergasted when he said yes. After five minutes he was breathing without strain in a normal rhythm - with oxygen.
My mom too never complained about being ill.
It may have been the New England upbringing thing.
