Brain plasticity is amazing, but rewiring the brain requires thousands of repetitions (reps). Activities of Daily Living (ADLs) are a great way to get the reps needed to retrain the brain.
Four examples show why two sets of ten cannot compete with ADLs.
1) Twice a day I open my hemiplegic (paralyzed) hand to grasp a tube of toothpaste so my sound hand can remove the cap. My hand opens again to hold the tube while I put the cap back on. In nine years I have opened my hand over 5000 times before brushing my teeth.
2) I have to turn 14 times to prepare cereal with a sliced banana. I have made this same breakfast for nine years so I have made over 45,000 turns. Add making a sandwich for lunch and preparing a hot meal for dinner and the number of turns I have made in the kitchen are in the hundreds of thousands.
