I am 69 and have had grey hair for a long time. I started on the black seed today. I'll see what it does for me.
Normally when I am in a store or cafe I ask for senior citizen's discount. I then show my ID for proof of my age. Usually met with a smile and they say it is not necessary. I then reply that I do have an honest face. (Having a little fun, really)
Hopefully I will get back to really having to show my ID.
