Study Notes
- Juggling impacts the brain.
- Decline in memory and orientation happen as people age.
- These changes are a result of normal aging that impacts the brain.
- The brain produces less serotonin.
- Serotonin affects the reward system, appetite, drive, and mood.
- Reduced serotonin can lead to sleep disorders, depression, and mood swings.
- Short-term memory declines, and the cerebral cortex thins.
- The cerebral cortex stores networks of knowledge and skills
- Less enjoyment and variety in old age means less dopamine in the forebrain.
- This process does not have to lead to dementia and Alzheimer's.
- Some people stay fit into their 80s and 90s.
Hippocampus
- The Hippocampus shrinks by 1-2% per year after the age of 20.
- The hippocampus is responsible for:
- Short-term memory
- Orientation
- Neurogenesis
- Any form of cycling movement can train the hippocampus.
- Cycling movements include swimming, cycling, walking, jogging, or juggling.
- 3 x 40 minutes per week of exercise is enough to slow shrinkage.
- Exercise helps produce new stem cells, which strengthen existing networks and cells.
Proven Success
- Exercise and juggling maintain the body and brain.
- Cognition works with the body through learning, feeling, and thinking.
- Regular exercise activates mitochondria, which are the power plants in cells.
- Mitochondria produce ATP (adenosine triphosphate), the universal energy carrier for all cells.
- Loss of healthy mitochondria causes aging.
- Muscles shrink, the brain shrinks, and memory and orientation decline with age.
- Exercise or juggling does not guarantee the prevention of aging, Alzheimer's, and dementia.
- Regular exercise and/or juggling can help against attacks to the brain.
- This can provide relief or alleviation.
