I’ve never had great knees, but this was a bit much. At 32 years old, I was limping around, struggling to go up and down stairs, and just feeling terrible about it. Thankfully, surgery and physical therapy helped and I have long since recovered. The most important lesson I learned from my bad knees is one that I see reflected in this week’s Torah portion. Parashat Tazria-M’tzora teaches us about our physicality; its focus is on the skin, hair, fluids, and organs that make up our bodies. We learn how out of our control those things can be and we gain some insight into our relationships with those entrusted with our care.
