what are the four dominant theories of aging?
3. Cross linkage
4. Free radical
- genetic clocks
- we will live longer if our ancestors lived longer
- wear & tear of cells
- immune response & T-cells ↓
- ↑ in infections, immune disorders, & cancer
- more prone to things (internal clock)
chemical reactions cause molecules to bind together and damage DNA & cell metabolism
Free Radical Theory****
- cell metabolism produces molecules with high energy electrons that disrupt function of every molecule that eventually damage cell membranes
- effects proteins & lipids
what is ageism?****
- A form of prejudice
- A belief that older people do not experience the same needs desires and concerns that younger people do.
Approximately half of all hospitalized patients are over the age of 65 (True of False)
