I've just been reading back.
re bread reactions - It could be the flour, or the yeast, or preservatives, or any other additive.
for me that can be milk solids or potato flour if they sneak that in
re getting up from ground / near ground - It can be hard to do that without putting a hand on the ground or another stable object. When I had my broken shoulder I sometimes would 'walk' on my knees to a chair for support. I need to put a hand down to get my feet under me. Beginners yoga had us walking our hands up to knees and thighs to go from squat to standing.
I watched a tv program that endorsed being able to rise from the ground with crossed ankles to begin, no hands ... as being a sign of positive health longevity ... they counted how many extra points / body parts needed to touch ground to get to standing. I just tried it and got 3, including a hand shift.
20 years ago I could do that while holding books in my arms. no longer. Maybe I leant against a wall to do it way back then. Anyway - the program suggested practicing to gain strength.
My recent attempts at fitness are to get back to regular weekly yoga classes, and walking as fast as possible daily.
Living this day, today
Take a reality check; Remember to breathe; Do what I am able to do.
Look for the good in all.
