People who have been diagnosed with mental health disorders tend to die younger than people who have not. Once again, average life expectancy for Americans today is ~77 years. Physical disease often accompanies mental disease. Therefore those who have a mental disease or disorder have average life expectancies of only ~63 years. This is certainly in keeping with considering homosexuality to be a mental disorder, as Lesbians live, on average ~69 years. And for Gay men, life expectancy is even less, at ~57 years. Coincidently, 63 is right in between 57 & 69.
