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.
Usually the security on death row is very tight, and the prisoners held there are subjected to special rules. If someone is convicted of a crime and sentenced to death, he or she will be transferred to a facility which has a death row or a space in which prisoners under sentence of death can be safely accommodated.
