Fellow Gen X’ers when you do retire will you start eating dinner at 4:00 PM?

Honestly I have no idea how or why my parents, my inlaws, my friends parents, and all the people in their 70s and 80s must eat so early. I am a young 57 when we go visit my parents or inlaws and plan to go out to dinner they are getting nudgy to go at 4:00 pm. When I ask what the rush is and they will reply “it gets crowded later”. Okay but if I eat dinner at 4:30 pm I am going to be hungry later. I refuse to be like that and eat mid afternoon. I have already told my kids if I start to do this then they need to do an intervention. LOL

Edit: I see people commenting about waking up early. I get up at 4:30 am Mon-Fri and get home around 4:30 pm. My wife and I don’t start the “what do you want for dinner” routine until 6:30 pm. I try to be in bed by 9:30 pm.
