I guess I'll pass

I heard an interesting commercial on TV the other day. No, not a political ad, I've been muting those.  This one was an ad for cosmetic botox.  All the warnings of possible side effects are enough to assure me that I never want to do this but one statement really made me womder.  The announcer said that this treatment would make the lines in my face look better.  What does that mean?  How does a line look better?  Is it deeper, more clearly defined, easier to see?  If I was considering this process I would want to be assured that my lines would become invisible, look gone rather than better.  Honestly, the thought of a face lift (better yet a full body lift) has flitted thorugh my mind from time to time - usually when I'm looking in the mirror - but when I consider the cost (and possible pain) vs. the long term results, I realize that I would much rather spend my kids' inheritance on travel.  Much more fun.
