bro this is village and people in villages still do follow same schedule , i saw this when i visited my village last in may 2018.They get up early in the morning at 4:00 and then start their daily schedule , by 12 in the afternoon they are done with their job, they eat and start to do some other activity and then by 8: 00 in the evening they are sleeping.They work really very hard , hence their body becomes very strong to fight any disease.
Upvot my comments and reply
