Farmers have critters, and large expanses of land that require or demand time outside of a 9-5 office gig.
Young people have excitement and energy that allows them a hectic life cycle which includes, all too often, self destructive activities that they miraculously spring back from . . . . until they're no longer young people.
What one has to do and the time they have to do it is the deciding factor.
I just got off the 'phone with my son in Florida who is now, and for as long as he and his partner stay awake . . trimming out new houses.
He loves the work and because the houses are empty, they can work whenever and for however long they want. He said it looks like a 2 or 3 AM "day"
As a dialysis nurse I function best waking at 2 AM for the 3:30 clinic opening. I found my deepest sleep rhythm had not yet occurred after 4 or 5 hours asleep, yet I awoke easily and functioned very well until the 3 PM closing time. I took great pride in running full steam between 4 am and 9 am, which before were toxic hours for me.
One thing that helped was getting up at 2 AM to drink coffee, take meds, and eat peanut butter. I went back to bed for about 45 minutes which satisfied my lifetime psychological need to “go back to bed”.
Even if I only got 3 or 4 hours of sleep, I still functioned well and was able to make up for it the following evening. Going to bed between 6 PM and 9 PM after those exhausting days is heaven.
Getting up in the 5 am to 7 am timeframe has always been torture. I told my family I would do the entire night shifts as a caregiver as long as someone covered me at sunrise. Something about sunrise induced sleep.
Try a wakeup time WAY off normal, I now seek early morning clinic starts at work.
