Personally, I think most humans need "a substantial support network." When I worked at the college library my friends and family was supportive of my job and the happiness it brought me. They were there to support me when I had the job from hell that made me literally physically ill. Zero and I have an online support network to discuss the special issues that only a service dog team will ever deal with in everyday life.
Often we don't recognize these support networks but we are social animals and naturally our needs and even our entertainment options (baseball or football team supporters-we got your covered).
It has become so drilled into our society that as people with past using and drinking problems we are special: so why should we be surprised to view the above context of "substantial support" as AA/SMART etc instead of just plain support like we do with the rest of our lives?
Just something I was thinking about today
