Replying to Thoughts on adult male age 40 who goes to bed between 6-8 pm latest

I know this guy who on his days off , always day drinks , and is in bed by 6pm , sometimes he will make it to 8pm latest . Usually on these nights he sleeps until noon also , and basically sleeps until noon every day . Plus takes naps every day and hides at work to sleep , takes naps at work also . So nsers, tell me your thoughts on this guys habits and lifestyle. He seems to think he's fine .
