But the very hairs of your head are all numbered.

"According to a recent study published in the journal Neurobiology 
of Sleep and Circadian Rhythms, the negative consequences of shift work might last for a long time, even after returning to a regular schedule.
“Shift work, especially rotating shift work, confuses our body clocks
and that has important ramifications in terms of our health and
well-being and connection to human disease,” said David Earnest,
professor.
“When our internal body clocks are synchronized properly, they
coordinate all our biological processes to occur at the right time of
day or night.
When our body clocks are misaligned, whether through shift
work or other disruptions, that provides for changes in physiology,
biochemical processes and various behaviors.”

and colleagues discovered found animal models with rotating shift work
schedules had worse stroke outcomes in terms of both brain damage and
functional impairments than those with typical 24-hour cycles of day and
night. Males had far worse outcomes, with substantially higher fatality
rates.
The researchers also observed increased levels of inflammatory mediators
from the gut in subjects exposed to a shift work schedule. “We now
think that part of the underlying mechanism for what we’re seeing in
terms of circadian rhythm disruption causing more severe strokes may
involve altered interactions between the brain and gut,” Earnest said."
