Well, they are lacking in Iron if they have anemia. Soooo an iron supplement.
If they support your feet, are comfortable and if they fit.
Based on biology of living things, some of the physical changes associated with the aging process are:
- Loss of bone mass
- decreased muscle mass
- thinning of the heart
- stiffening of the arteries
- decreased lung capacity, etc.
<h3>What is aging?</h3>
Aging is a natural process that occurs in living organisms when they become older or as time passes.
During aging, certain physical changes that usually result in reduced abilities of normal body functions occur which are the observable features of aging. They include:
- Loss of bone mass
- decreased muscle mass
- thinning of the heart
- stiffening of the arteries
- decreased lung capacity, etc.
Therefore, some of the physical changes associated with the aging process are:
- Loss of bone mass
- decreased muscle mass
- thinning of the heart
- stiffening of the arteries
- decreased lung capacity, etc.

Answer:
Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker
Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon
Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.
N/B; Harder to generate action potential in demyelinating disease
axon diameter( bigger diameter= less resistance= faster current).
