EG, I agree, too!! Don't rely exclusively on your BMI...
Though I've seen my BMI (I think that's what my scale is calculating) around 16, I could see in my face (I might even have photos to show) that it was too LOW, despite the ex-wife insisting I not get fat, or "overweight".
I felt good at 70kgs, but only for a while...I actually feel better at 75kg, but some pants have become a bit snug! I would like to see myself back at my average of 73kg, but only if I'm equally feeling well, and doing well.
I'm sure a lack of nutrition and a proper diet was missing during my days of looking like a "skeleton", as the ex put it; which is why after I shot up to 80kg, I finally leveled off at an average 75kg from a better diet. Though I feel work wears me out a lot, for some reason I do feel a little better after going to my Iaido class...speaking of which, I got class tonight!!!
