Longing for the Winter - Question

Greetings,
BOM is my homepage - Australia’s Bureau of Meteorology. It’s dead accurate and gives me my first daily shock. It lists what to expect a week ahead. Now there are 7 stinkers lined up - all about 35 degrees and higher. They put dog Rusty and me into a torpor. For 2 months we vegetate, soaked in intense self-pity.
To save the planet I fool myself with an inefficient fan during the day. For the night it’s airconditioning in the bedroom. Each afternoon, dog Rusty squats in front of that door; stares at it like at the Pearly Gates with paradise behind them. Which it is. Of course, it’s much too noisy to sleep. So the day’s brain is foggy. We are summer zombies yearning for shivers again, and be cuddled by winter’s knitwear.
The strange thing: years ago living in Sydney I loved the beach and sun and summer. Now it’s a curse.
Question: is there something wrong with me, or do all oldies - say above 60 - wither under the sun?
Klaus and Rusty
