Growth

I am convinced that people can and do change in both intellect, attitudes, and outlook as well as physical growth.

On a personal level I myself have grown considerably since my salad days, and for the better too I might add. It's all to do with our brains gathering experience through our life events, and the culmination of all this is maturity.

Note that I have substituted the word 'change' for 'growth', as I believe that it was you meant in the challenge description, rather than a change of form, which would be rather nice if it were possible.

I do believe my challenge is complete.
