i like to run. i've 3 children.
Yes, I agree there are almost no barriers to entry for it and that's convenient have you ever experienced a runner's high? No, I mostly go jogging. What is a runners high?
Its when you achieve this state of blissful flow after pushing your body to its limit on a run.  Yes its difficult to achieve. very few people are able to do so. Maybe, I can't say for sure. I have experienced something like it before but not often enough. Only when I get free time from my editing job haha. Could be a physiological or biological phenomenon. we still have much to learn about it.  One, I am moving out soon to have more space for my wife and him. 
i don't think i have reached such a state before are you part of the few? do you run frequently? what are the reason behind it? so how many kids? hope it wouldn't be far from them?
it is when you eat a lot and get sleepy . it is when you eat a lot and get sleepy . yes , but you can not feel it after you have been running for a while . you should run a marathon , it gives you natural highs . yes , but you can not feel it after you have been running for a while . good for you , i have already settled down
It's basically when eclampsia has progressed to the point that your blood won't clot and your organs start shutting down. Yes, but not impossible. I see, that's too bad but maybe there will be more marathons you can participate in in the future. Ha, same.  Are you at work right now? Maybe. I think some people are just born with it. That is awesome. Having more space is always a plus.
I like jogging more than running myself. So I guess I'll never get a runners high while I'm trotting along. Yeah it is amazing what happens to the body when you run, activity of enzymes and hormones that stimulate the muscles and the heart to work more efficiently. Do you think that's because your heart rate is quicker during a short run? Is there any sports that you do regularly? I don't think there is one cause. Sounds like your dad needs to get his priorities in order.
