Growing old is part of life, but the 'old' part is nothing to write home about. Live your life to the full for as long as you can, because when time starts to run out the last part of your life can be a pain, literally. Our bodies grow old but, for the most part, our minds are still younger than this shell that carries us through this world. I'm 68 (in November) but in my mind I am still 18 but this bloody body won't comply with what my 18 year old mind wants to do. Stay young, don't grow old; not that you have much to say about it lol.
As for the worst thing about becoming an adult, is losing the innocence of youth.
