Life's a gas

Numerology is defined as the study of numbers, as the figures designating the year of one's birth, to determine their supposed influence on one's life, future, etc.
Do you see the bolded number here?
It does have an influence on my life, but it's no one's birth year.
Okay, well it could be, but they'd be dead by now.
Of course the dollar sign is a dead giveaway.
It's not my credit card balance, I could only wish.
I'll tell you -- but quick, grab yourself a paper bag in case you start to hyperventilate.
(I was gasping for breath when I opened it myself.)
This is my gas bill for usage in February.
Now, position that bag over your mouth and breathe in slowly and out slowly.
