Of primary cosmic rays, which originate outside of Earth's atmosphere, about 99% are the nuclei (stripped of their electron shells) of well-known atoms, and about 1% are solitary electrons (similar to beta particles).
Grief is a natural reaction to loss, and the breakup or divorce of a love relationship involves multiple losses: 1  Loss of companionship and shared experiences (which may or may not have been consistently pleasurable) 2  Loss of support, be it financial, intellectual, social, or emotional.
Grief is a normal response to a significant loss, but can become a complex psychological and emotional experience. It is common for someone who cares for a person with dementia to experience grief. This can occur while they are caring for the person and after the person has died.
