I moved to a bungalow when I was 46 because I'd always liked them and moved to a place where they are affordable so grabbed at the chance. So easy to maintain, decorate and keep clean, and usually nice sized gardens.
I've since done up 3 more as cheaper ones usually need updating [new kitchen, bathroom, decoration, flooring, garden tidy up. They are quick to sell on and always a market for ones in good order. I'm probably now in my last one, which I love, and am now 76.
They are so practical to live in, no traipsing up and down stairs to a toilet or bathroom, or to clean them or to put clothes away etc. In winter heating doesn't disappear upstairs [have a well insulated loft].
On hot nights I open small top openers in rooms and keep the door open so air moves through, no problem.
30 years of living in bungalows and I do not have 'bungalow legs' believe me...but I'm active, always doing gardening, decorating, woodwork etc. use stairs if I'm out anywhere/visiting places and walk as much as I can. Maybe that's why.
