Yeah, I agree. I want weight loss and health to be my new obsession, too!
About three or four years ago it was. I was on Jenny Craig, doing yoga, swimming, biking. I lost alot of weight! But then I got into video game testing as a job.. where I worked A LOT of overtime.. meaning I was on my butt all day. I gained alot of weight.. sigh. They even fed us.. ugh.
I haven't been able to get into the swing of things again.. I don't have my bike anymore.. there are no more yoga classes around here except in the gyms. And there really isn't anywhere(that looks clean..) to go swimming around here. I used to go swimming at my friends house.
I think that's a great idea! Replace one obsession with another and you're good to go.
Chiroptern- Perhaps you could invest in a good yoga video? You could do that in the privacy of your own home whenever it suits your schedule. My hubs is also a software test engineer so I'm familiar with the amount of butt-sitting involved. There are work-around solutions to your obstacles if you use some creative thinking.
