I thought that pants were getting longer, too. But then I went to my regular doctor for a check-up and the nurse asked me how tall I was. I told her 5'5", just as I always do. She measured me and I was only 5'3". I didn't believe her, and she did it again and showed me where my head hit.
Where did those extra two inches go? No wonder I'm 'fluffy' - I'm same weight but getting shorter!
