Why have women started using luggage as handbags?

Why is this cool?  Killing the crooks of our arms and wrists.  Throwing our backs out of alignment.  Then to top it all off, posting video after video bragging about how weighed down it is with stuff?  So many things that we don't actually need.  Aside from the phone, charger (for the smartphone users), lotion, lip gloss, comb/brush and a small agenda how much do you really need?  5 perfumes, 2 desktop agendas, a notebook, 3 magazines, a wrench, 3 spoons, a pair of shoes, an Ipad, a Nook, a Kindle...... I can go on, because they do.  I'm not bashing.  I'm just asking why????  Why is this the new cool, fashionable thing to do?  So, you are wondering why your arm hurts?  Maybe your handbag is cutting off the circulation to your arm.  Back hurts?  Handbag again.  Shoulder is sore?  Handbag..... Need I say more?  I think I'll post a "what's in my bag" tag.... Enjoy!
