Clearly, you never had a problem walking. I did for a year and finally had it fixed with stents being placed in my legs. Today, yes, it doesn't bother me to talk at TLV (or any other airport) but my last trip before the stents (TLV-JFK) was sheer agony for me. Terminal 4 in JFK requires a walk to the passport section that is slightly shorter than the walk to Manhattan.
