Meaning exercise-induced hypoxia and experience with simulated high altitudes (train low - rest high).

God's chastisement will, actually, be an act of His Mercy, even if that means some of His faithful will suffer, too. I look forward to it, too. Time to purge.
Punishment by God for our sins and lukewarmness will be allowing iniquity and degeneracy to continue leading up to Antichrist's public emergence.
