Older adults usually don't get mono, because they have immunity to the virus. Mono can be spread through contact with saliva, mucus from the nose and throat, and sometimes tears. Because the virus can be spread through kissing, it has earned the nickname the kissing disease..
Death row is a prison facility or area of a prison where people under sentence of death are held to await their executions. In nations which practice the death penalty, not all have a facility of this kind; some hold their prisoners among the general population or in a generic area of a prison.
Since the death penalty was reinstated in 1977, about 70 of the state's condemned inmates have died of natural causes. Another 24 killed themselves. (In the last 10 years, the suicide rate on California's death row was 15 times higher than the statewide rate.) About half a dozen condemned inmates died from other causes like drug overdoses and murder.
