The energy is up, mental clarity up, calories way down, all good things. How long will it last? The training effect from the last 20 plus years of training will always be there. Have you tested your strength since you quit training, even with light weights? What adjustments will you make if your energy and mood start slipping?
there is no training effect. Like all else, thr body adapts to whatever you choose to do or not do
You die with yhe same strength you are born with... how well you are able to make use of it depends on many factors.
There is no actual strength increase as there is no muscle size per se to be gained.
What everyone me included were "taught" is that muscle grows. No it does not. You only "gain" various degrees of inflamation.
When you train you educate your mind to be more efficient at something. Hence we are taught about strength gain
Truth is that you come into this world with both strength and muscle
