What does your faith or belief system teach about the mechanics of death? Is there an angel of death? Is the soul extinguished or somehow removed from the body? Is there an inner light that expires? Is there perhaps "the kiss of death"? Are there ways to avoid or postpone death? Any other details are greatly appreciated.
In main-line theist Hinduism, the do-gooders are sent some form of a luxuriously fitted aircraft (vimana) with courteous flight attendants and honorably escorted to the court of the God of Death, Yama, who would then ask them their choice about what they choose first, hell for a short period for some inadvertent mistake they might have done, or heaven, which in their case will be longer. The evil are dragged by hair by Yama's hideous-looking messengers riding he-bullocks and dumped before Yama. They may get a short period in heaven for any inadvertent good that they might have done, which will be short in their case and a longer sojourn in hell. They are not given any choice.
No. The soul is not extinguished, it is eternal. But eventually, all return to the world in a new life and go through the grind, unless they attain nirvana, moksha, enlightenment, by any of the three means - knowledge (Jnana), deeds (Karma) or Devotion to Deities (male or female - Bhakti). This is completely secular and does not depend on what beliefs they might have or which Gods they might be worshiping.
Avoidance of death is possible in rare cases for a certain period of time, depending again the three things mentioned above and the will of deities. But accept for the fortunate few in Hinduism, death comes to all (Theist Hindus believe that only eight people have been granted immortality). They are:
Ashwatthama, King Mahabali, Sage VedaVyasa, Lord Hanuman, Vibheeshana, Krupacharya, Lord Parashurama and Sage Markandeya, being the eighth.
It is said that one who always remembers this, will live for 100 years without any ailment.
"Ashwathaama Balirvyaaso Hanumanshcha Vibheeshanaha
Krupaha Parshuramascha Saptaitey Chiranjivinaha
Saptaitaan Samsmareynnityam Markandeymathaashtamam
Jivedvarshshatam Sopi Sarvavyadhivivarjita"

However, in my own Advaita-based belief, nothing like that happens. Death is just failure of a machine and its chemical disintegration by various means - internment in a grave, cremation, exposure, etc.
