Age is Just a Number

We have all heard the saying.  But do we all really believe it?  I think it depends on what you are talking about.
When talking about relationships there are a couple different ways to look at things.  A healthy 56 year old man who is married to a 44 year old women (12 years difference) doesn't seem too weird or unusual to me.  However when I think of a 31 year old women dating a 19 year old college student (still 12 years difference) I instantly furrow my eye brows in disgust.  Why is this?  Is it because the gender roles were reversed and now the older woman is chasing after the younger boy?  Or is it because the younger person in the relationship is not even of drinking age yet?
Recently I posted a Facebook status that read "life is still one party when you're still young", it's lyrics from the a song sung by Shaggy.  Within a couple of minutes of posting three adults had commented on my status.  One man, who is in his upper 50's wrote "at what age does the party stop."  This dad of one of my friends is a total kid at heart.  He water skis, snow boards, rides motorcycles, jams rock music at the high school football games, and knows how to throw back a few beers on the weekends.  When other adults commented after him saying they agreed with him it made me smile.  There are a lot of things I am not looking forward to when it comes to getting older.  But these adults definitely still know how to have a good time, which makes me hopeful.  All I need to do is remember, age is just a number after all.
