Question: What the must challenging thing you have don?

In science the most challenging thing I have done so far is explain why patients with big balloon shaped hearts and scars get dangerous electrical loops in their hearts. By using a computer I was able to calculate how it happens by taking information from medical images and applying the physics of electricity. I made a lot of mistakes for about a year, but then I finally tried a trick to put the small scars into the calculations, and then the calculations worked out and I saw the loops!
