A/J,
if you look at your life, and each and every day, it's kind of like setting initial timing. totally have to look at your compression, and you must know what the cam was installed at, and if your grand children are the spark plugs in your life, and your fuel is the communication between you and all your loved ones, then you must have High octane to be sure that the spark has something to ignite. We all know families have explosions, but when it's contained with in the cylinders then it becomes a controlled explosion leading to a healthy family, which I'm sure you have. Your birthday is significant to all those around you, and though at times you may feel underappreciated, you can rest assure that each one of you children, and grand children will be thrilled to make your day very, very, memorial. So be sure to keep the compression up, the gas intake (don't forget to exhaust the gases out), and be very calm you'll have many more miles left, with many more bridges to cross, many more loved ones to enjoy, many more black marks to lay, and you'll be very healthy, wealthy, and wise.
I'm sorry I was a little lengthy, but I wanted to make sure that you'll enjoy your special day to the fullest of what it was meant to be.
So, have a happy birthday and I'm sure you'll be blessed with many gifts, health, and loved ones all surrounding you on your on very special day.
Happy birthday
