Middle-Aged? Elderly? Senior?

Inspired by some hubbub over at The Daily Republic newspaper, blogger for Bankrate.com, Dr. Don Taylor raises an interesting question. What are the right words to use when describing … for lack of a better word … the elderly? And when, exactly, should that term apply? Do you think of yourself as elderly? Do you object to being called a senior citizen? In many cultures, the elderly are revered, but here, where 50 is the new 30, maybe it’s also true that 70 is the new 50, and no one wants to be called old.
