Yes skinny all whippets which all of their generation are aunts/uncles now in 70s & 80s (grandparents passed) - but they all ran around after 6-8 kids each whilst fitting in part-time cleaning, waitressing, caring jobs on top. Never sat down always cleaning.
They didnt learn to drive until they were in their 40s, barely drank - but smoke like chimneys.
They always cook from scatch eat simple meat+2veg meals (non-UPF), rarely ate out or had takeaways - except fish and chips occassionally.
