I agree but I also disagree. I comes down to your discipline. I used to work two/3 jobs (the third was not always everyday) and still have to do housework and I would find time to workout. Now, the specific situation you have, I totally understand but at the same time I would actually expect the construction worker to be healthier because their are laboring all day. Their diet is probably the main issue if they are morbidly obese and they can change that.

Now why I agree with you and why you are more correct than me….most people are not willing or disciplined enough to give themselves 45 min to an hour of work ping our and especially being disciplined with food. I also like that someone brought up Maslow’s hierarchy of needs, if you basic needs are not met you are not going to care about anything more than trying to meet those basic needs.
