In Armenia I would choose a cooler place, because everything will grow in the garden anyway.
My father will soon be 80 years old. And every day from morning until lunch he potters around in the garden. And in winter he comes to the garden to look after the house. People who are active in the fresh air are healthier and live longer.
Yeah, he's in incredible shape for his age. But that's a life of being so active and taking care of yourself. Still mentally sharp too. Managed to learn a lot about (long) нарды from him, after so many games in a row of getting absolutely destroyed by him haha. And that's after we would have a few shots of vodka or cognac over lunch ;^)
It's nice to see that routine still in the elderly in these regions. They have things to do. They don't just get stuck inside and deteriorate. Keeps them happy and active. Probably means a lot to them if their produce ends up being enjoyed by their family too.
