Baby Boomer Pat Baker has been working in the field of aging for 45 years — mainly with the federally funded Older Americans Act programs, which have been providing seniors with services such as meals, caregiver support and transportation since 1965. When she first started, she was seeing people in their 60s and 70s participating in the senior programs. But now, as she herself retires, she has noticed a change. Participants are now in their 80s and 90s.
