The Institute of Gerontology (IOG) at Wayne State University conducts research on the behavioral and social aspects of aging.
 Located in Detroit, Michigan, the Institute has a strong focus on urban issues, especially disability, mobility and transportation, financial challenges, and disparities in health between ethnic groups.
 Faculty at the Institute are jointly appointed with a home department in a complementary discipline, such as economics, physical therapy or nursing.
 The Institute also maintains a Lifespan Cognitive Neuroscience of Aging laboratory currently profiling brain changes in normal aging through traditional testing and magnetic resonance imaging (MRI) of participants brain structure and function.

Henry Rathvon is a puzzle writer.
 He and his partner, Emily Cox, wrote The Atlantic Puzzler, a cryptic crossword featured each month in the magazine "The Atlantic Monthly" from September 1977 to October 2009.
 (After March 2006, the Puzzler was published solely online at The Atlantic's website.)
 They also create acrostic puzzles for the "New York Times", cryptic crosswords for Canada's "National Post", puzzles for the US Airways in-flight magazine, and (with Henry Hook) Sunday crosswords for the "Boston Globe".
AARP The Magazine is an American bi-monthly magazine, published by the American Association of Retired People, AARP, which focuses on aging issues.
Merle is a pattern in a dog's coat.
 "Merle" comes in different colors and patterns.
 Some have blue patches throughout and are considered blue "merle"; same with red, and chocolate, although some describe merle as only a "pattern".
 DNA testing identifies the "Merle" gene but not the variety of colors and patterns seen in the coats of the dogs with the gene.
 A dilute black (BB or Bb) dog is generally known as blue, but a dog with a merle coat does not test BB or Bb but still is a blue dilute from the "merle" gene The merle gene creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well.
 Health issues are more typical and more severe when two merles are bred together, so it is recommended that a merle be bred to a dog with a solid coat color only.
Merl Harry Reagle (January 5, 1950 – August 22, 2015) was an American crossword constructor.
 For 30 years, he constructed a puzzle every Sunday for the "San Francisco Chronicle" (originally the "San Francisco Examiner"), which he syndicated to more than 50 Sunday newspapers, including the "Washington Post", the "Los Angeles Times", the "Philadelphia Inquirer", the "Seattle Times", "The Plain Dealer" (Cleveland, Ohio), the "Hartford Courant", the "New York Observer", and the "Arizona Daily Star".
 Reagle also produced a bimonthly crossword puzzle for "AARP The Magazine" magazine, a monthly crossword puzzle for the Society of Former Special Agents of the FBI, and puzzles for the American Crossword Puzzle Tournament.
Brian K. Kennedy, PhD, is the former President and CEO of the Buck Institute for Research on Aging in Novato, California.
 Having started in July, 2010, Kennedy was asked to resign in October 2016.
 Kennedy's resignation raised serious questions about Buck Leadership.
 Formerly, he was an Associate Professor in the Department of Biochemistry at the University of Washington.
 He obtained his PhD from the Massachusetts Institute of Technology in 1996.
 It was during his graduate studies with Dr. Leonard P. Guarente that he initiated studies of the biology of aging, where he identified Sirtuins as key modulators of longevity in yeast.
 One focus of his current lab still centers on Sir2 and aging.
 After a Postdoctoral Fellowship at the Massachusetts General Hospital Cancer Center, where he studied mechanisms of tumor suppression, he began an independent position at the University of Washington and turned his focus back to aging biology.
Emily Cox is a US puzzle writer.

 They also create acrostic puzzles for "The New York Times", cryptic crosswords for Canada's "National Post", various puzzles for the US Airways in-flight magazine, and Sunday crosswords for "The Boston Globe".
 Cox and Rathvon are now also contributing cryptic crosswords to the Wall Street Journal on Saturdays.
Financial Gerontology is a multidisciplinary field of study encompassing both academic and professional education, that integrates research on aging and human development with the concerns of finance and business.
 Following from its roots in social gerontology, financial gerontology is not simply the study of "old people" but emphasizes the multiple processes of aging.
 In particular, research and teaching in financial gerontology draws upon the "four kinds" or four lenses through which aging and finance can be viewed: population aging, individual aging, family aging, and generational aging.
 The field.
 While it is not always true that "demography is destiny," demographic concepts, issues, and data play a substantial role in understanding the dynamics of financial gerontology.
 For example, through the lens of population aging, demography identifies the number of persons of different ages in cities and countries—and at multiple points in time.
 Through the lens of individual aging, demography notes changes, typically improvements in human longevity.
 Beginning in its founding years in the beginning of the 21st century, one primary interest of the field has been on the baby boomers and their relationships with their parents.
 The impact of these two kinds of aging on finance are reasonably apparent.
 The large and increasing number of older persons population aging in a society, however "old age" is defined, and the longer each of those persons lives [individual aging], the greater the impact on a society's pattern of retirement, public and private pension systems, health, health care, and the personal and societal financing of health care.
 The focus on boomers illustrates the other two lenses or "kinds" of aging.
 How boomers deal with the social, emotional, and financial aspects of their parents' aging is a central aspect of family aging.
 And how boomers may differ from their parents born and raised twenty to forty years earlier, and differ from their Generation X and Millennial children and grandchildren, are substantial aspects of generational aging.
