Quote from Picaso:
This explains your wanting to get back in shape 
Hey, who knows? she's still single
That Emily is still single is interesting. I read somewhere that she is in no need of being married and is content being single. There are many attractive women that feel this way, and the reasons are as varied as people are. Eventually love will find her, but there is some impediment there, perhaps fear.
Most people don't realize this, but it is having children that puts an enormous stress on most marriages in this country. The failure rate is so high, why bother right? It is a horrible tragedy not to understand the reason for failure though - couples need help, tax breaks, and they absolutely need to put their foot down that no matter what, at least once a month they get alone time away from the kids, preferably in some romantic environment to connect again. The people that have successful marriages seem to follow some sort of plan like this, imo, or they don't have kids at all.
I have been reading that now, some ungodly number of people are living single lives in the US. Not only is living single way more expensive than sharing an apartment, cooking for two is not twice as expensive as cooking for one, but the health benefits that the peace that companionship can bring to a person is well known, especially men. People don't seem to like each other that much anymore I guess.
As to motivation to get in shape, it was not any one thing, but an amalgamation of events that ignited a fire in me. I am not picky in this way, I will take my motivation from where ever life dishes it out to me. I consider it a gift.
