It can be frustrating to see such ignorance from acknowledged
"authorities", and irritating to see the bias that accompanies the
How to turn this to a positive?
Q: Certain organizations offer, for a fee, to freeze individuals as
quickly and non-destructively as possible following the legally
defined moment of death, with the intention of halting further
biological breakdown until technologies are developed that may reverse
the damage caused by both the preservation process and the original
Notwithstanding the cultural and legal impediments, what are the
various modes of biological breakdown that must be addressed by these
And then you "simply" make this additional viewpoint readily available
to the students...
But seriously, I think an effective general approach to making
progress on these issues is by raising awareness through increasingly
shared knowledge platforms. The days of "authoritative" textbooks are
