To those in their 40s and 50s, would you work if offered a 4-group 2-shift schedule?

Since I'm in my 30s now, I think I would do it if offered a 4-group 2-shift schedule.
But I'm worried that once I hit my 40s or 50s, shift work might take a toll on my body.
If it's a 4-group 2-shift schedule that guarantees 4 to 5 hours of sleep,
do you think you could adapt immediately without worrying about your health?
