Numbers that scare me..

I am not a person that is worried about numbers for the most part, I don't really mind my age number, I don't get to worked up about the number of dollars made/ spent (you can't take it with you ) Even the random high blood sugar of 300 or 400's doesn't shake me much, cause I know we can get it down.. but some numbers do upset me..
Today I was sitting at my computer surfing some cool home school sites when from the living room I hear.... uh! Mom come now! I'm 39!!!

Fear was in that voice, and fear sprang in my heart, because this 39 happened while hanging out on the sofa playing x- box with his brother, it came out of nowhere.. numbers this morning have been good, no extra activity to account for it, no decreased appetite or illness to blame it on.. lunch was pizza which tends to cause highs, not lows... So if for no reason at all we plummet to 39, my brain begins to wander... what ifs.... what if he had been at the lake, swimming in the deep... what if he were driving, ( it won't be long) what if it was 3:00 in the morning and I hadn't bothered to get up and check his sugar ( some nights I sleep through nighttime checks) .... was he close to having a seizure? or losing consciousness or worse?
Lows are scary, they are scary for the person having them and for the people witnessing them. They are also a part of our life, and for the most part we manage them without much fuss. Funny how saving the life of your child becomes so routine, when I heard 39, I jumped up grabbed the dextrose tabs and pixie sticks and within mins his blood sugar was back up to 77, within seconds of hearing, "come now" I had mentally reviewed where the 'BIG RED" (glucagon ) kit was and the cake icing (just in case). Numbers like 39 will continue to haunt me and keep me up at night, because numbers like 39 do scare me.
