Rubyee,
1. I love jogging / running - I don't know what kind of hope you were looking for (I'm no Obiwan) but best of luck. Great exercise, great for relaxation, and you can take it almost anywhere.
2. I'm going to suggest being careful with your form. The people I know who have long-terms issues with jogging/running have issues with their joints (mostly knees and ankles) and this is from poor contact with the ground.
3. If you decide to stick with it, get the best running shoes you can. It's worth it.
4. As far as endurance goes - I'm going to suggest starting small - around the block is fine...whatever you feel comfortable with. Also, I've known people who did the walk a while, jog a while thing...and eventually you find you can jog your whole goal distance/time.
4. Ummm...I've never had that particular problem with running with breasts. All I've got is nipples, etc. But I did look in
Runner's World for you: if this doesn't do it, it's a pretty good resource. You might go to a local runner's shop and ask someone there for their advice. Or wait for a lady-type to respond to the thread.
Either way, best of luck. Crap, while I'm at it (and I'm also not the small bald man from Rocky) - but let me just go ahead and super emphasize stretching, before and after. Will save injury down the road. Also, I've been trained to stretch after breaking a sweat - so that the muscles have warmed up.
