As was posted earlier by I think Lisa (my apologies if this is incorrect), no matter what, the body changes as we get older. Gravity affects us all. My tummy will never be the same as when I was 18, but you know what, I am not the same person I was at 18 and for that I am truly grateful. Each year (I noticed many changes after age 35) has brought new changes, but also a new acceptance of who I am and I happen to like myself and be more comfortable with me with each passing year. Stretch marks and all.
