How much have you changed physically over the last twenty years?

If you were to look at a photo of yourself which was taken 20 years ago and one which was taken today, would there be striking differences? When I look at photos ( then and now ) of celebrities I often see no resemblance between his/her younger self and how he/she is today, a total stranger in some cases!

As for me, I like to think I haven’t changed dramatically. Of course I have put on a lot of weight since then, but there doesn’t seem to be a night and day difference other than the extra kilos. I am not saying that I haven’t aged a day, just not in a dramatic way.
Do you see major differences and big alterations or are you essentially the same?
