Here’s an interesting statistic from a study conducted during the 1980’s.

Men who kiss their wives (or significant other) before leaving for work:

• live longer
• get into fewer car accidents
• and have a higher income than married men who don’t!

So, you’ve got some reasons on several different levels to kiss your woman more frequently. 

And another note:  if you increase the kissing, you’ll get more sex.  Duh!
