retardboi, when I look at the pictures and brief descriptions of the teams (reference your post #173), I find these:
team 3: older couple
team 6: older women, wearing bizarre bracelets
Your concern for the "older couple" is hopefully misplaced. None of the couple on team 3 or the older woman on team 6 appear to me to be more than their 40s in age. I hope you are not suggesting that 20-somethings will win over 40-somethings. It obviously depends on the tasks they have to do. The non-fit Mardy/Mariso did pretty well in ARA1. The non-fit Henry and Terri did pretty well in ARA2. The marginally fit team Bernie and Henry lacked by one year Bernie's age 39 for making the 40 something club and they did well. These teams all came in around 4th or 5th place. There is no reason I can think of that an older couple should not be competitive up to and in the Finale for Amazing Race Israel if they are mentally and physically fit.
