Is 30 really the new 20?

I am rapidly approaching 30 and I feel it. I think older people just say 30 the new 20 or 40 the new 30 etc... because they just don't want to get old. Learning to accept my age and ever changing body has brought me peace that I never thought I needed. Not accepting the fact of getting older kept me unsettled and always anxious. I am glad to accept getting older because now I discovered who I am. When people are younger that is when you are soul searching, so unless u want to soul search forever accept your age and be comfortable with who you are.
