Astounded: 60 year old woman thought my natural gray hair was silver dye!

Yesterday my fiance and I were at the laundromat. There was a lady there who was wearing a military uniform cap. I thanked her for her service as I am an Army brat (both of my parents are retired Army). She complimented my hair and told me she had family members pay $3000 to dye their hair silver! I was astounded. I told her my gray hair was natural as I'm 47. I honestly was shocked when she told me she had just turned 60, as her face looked younger than mine! I honestly thought she was in her early 50s!
