Speaking about not missing meals.
I retired in 2011. In the 6 years I have been retired and not doing a damn thing I have lost over 60 pounds. Now back to what I weighed when I was in the USAF. I walked some early on, 2-3 miles every morning, but blew out my knee portaging on fishing trip about 4 years ago and have not walked for exercise since. Just getting out of the stress made a huge difference. I did basically stop drinking booze, altho I may have a beer once every month or two. Bigger change was due to stopping the consumption of diet pepsi. No sodas anymore, lots of water.
Sorry to pat myself on the back, proud of it, but something I could have done long ago if I had just put my mind to it. Stress is a bad hombre.
I do get up early every morning, feed the deer and work in the woods out back getting rid of buckthorn and garlic mustard, a bit every day so I guess I cannot say I do not exercise but it is not boring like walking. Mama Doe brought her two new fawns up in the yard yesterday and paraded them around for me. Such cute little things, crow-hopping in the yard. If you ever want to give a deer a treat give them a Pink Lady apple, they love those better than anything else.
