Just turned 58... but my DH and I prefer to use what he calls the "10-point" scale... that makes me only 5.8 and he is 5.9 :D
We feel it helps us relate to everyone, the 4.4s, the 3.6s, even 2.7s or 1.9s!! ha ha
Now before your DH thinks those in the 50s are OLD, ask him how "old" I was when, after retirement at 56, I went back to school to become a Physical Therapist Assistant? Yes, it was tough, but I'm now a PTA and loving every minute of it! (Especially since I'm not working full time and have more time to quilt :D )
