A colleague of mine told me that "Right now you are the oldest you have ever been and the youngest you will ever be." I don't believe this is the case.
In my mind, the idea that he is trying to articulate is "will ever be, henceforth." When I hear "will ever be" I think that it includes the past, but I don't know which tense "will ever be" is in, technically.
His use of the word 'will' makes it seem like he's talking about the future, but he also uses the word 'ever' which means 'at any time'. There must be some sort of complex interaction between these two words, I just can't figure it out.
My best guess is that while he definitely states that the evaluation should include future dates, he doesn't carefully exclude the past, leaving this open to whether you think that 'will' or 'ever' is the more important word.
