So, CTlawyer, you are stating that you were taught that looks matter in a shidduch. I was not taught that, but I practiced it anyway.
I think the fact is that people do not get thinner as they get older. Excess weight creates genuine health issues in addition to cosmetic issues. I believe that overweight and obesity among millennials is substantially higher than it was among baby boomers at the same age.
Let’s not kid ourselves. Weight can become a weighty problem. Face it: the thinner you are when you are 20, the thinner you will be when you are 50.
