Oh yeah, the moany, always-tired, always-weary, multiple-ailment man. I have one of these. I don't know if it's a slightly older man thing, coz my DH didn't start to get like this til he hit late 40s. (5-6 years ago.) Always soooo tired, always soooo weary, often feeling soooo rough, and as pps said 'off to bed early some nights' (9pm) because he is 'just not feeling right at all.' (In a weak little voice like other posters have mentioned.) Shuffling around with his back hunched over, blowing his nose (but nothing is there!) 'coughing,' and just grunting as he goes to take some paracetamol ... And as he walks off to the bedroom, yes, it's the SIGH! 
If I have a cold, or sore throat, or headache, or any kind of pain, he has it too, and it's always worse. Does my head in! He hardly ever wants to do anything or go anywhere and sits in front of the TV 80% of his waking hours. He has no hobbies or anything that takes him out of the house. I don't know how I will cope when he retires! At least he is at work some days! I have to stick a firework up his arse to get him to come out with me, and he NEVER goes out without me.
He has had about 10 different 'ailments' in the past 5-6 years too, and even seen some specialists. Soooooooooooo many things 'wrong.' His heart, his back, his shoulder. his jaw, his kidneys, his knee, his wrist, his ears, his head - (thinks he has a brain tumour,) etc etc etc. But despite multiple tests and scans and x-rays, nothing has been found. He is most annoyed and disappointed. 😆
To be honest, I hope I never get really ill - to the point where I can't do anything for myself, and need care. Because I truly believe he won't step up. He can't stand me being ill (if I have a tummy bug or very bad cold or am laid up for a day or two with a migraine.) He sighs and huffs and puffs when I ask for a glass of water. Like I am really bothering him. I feel such a nuisance. (Yet I am like a paid nurse when he is ill... on the few occasions he is genuinely ill)
I also think he won't take too kindly at having to be my 'carer' because he is the 'ill' one, the one who has all these ailments, and just how DARE I have something worse than him? 🤒
