Still 18?

I used to say that I feel like I am still 18. But not anymore. Though my mind wants to think that I am still 18, the body is a different story. I tire easily, digestive system is sluggish, hair is greying and wrinkles are so much more visible. Aging is definitely a reality. Can't deny this fact. *sob* *sob*
I think I really must resort to taking hgh supplement .....at least to slow down the signs of aging, if not totally stop them.
