Neighbour issue - But not the usual sort!

As others have said, he has made it clear he wants to be left alone and you should respect that.  But do keep an eye on him from afar.  However, if I were you I would still try and hold a hand out to him occasionally just in case things change and he's too proud to ask after his grumpy exchange with you.  Even if it's just once a year - maybe drop him a Christmas card and maybe invite him for Christmas lunch or even offer to take him some lunch on the pretext that you always have loads left over and it would be a shame to waste it?  Small steps might get him talking to you, if it doesn't you've lost nothing, just don't hassle him.

I agree with the others - he’s made it very clear he wants to be left alone so you have to butt out at this point. Contrary to popular belief some people are actually happy by themselves. I know I’ve had to have a word with my neighbour about overstepping boundaries - looking in my front window when I didn’t answer the door immediately (I was in the bathroom).

I think the most I would do would be a Christmas card along the lines of:

”Dear Mr X, [usual seasonal greeting]

You’ve made it clear you want to be left alone, and I respect that. I won’t bother you again. But if you ever change your mind here is my phone number [number]. I’d be very happy to hear from you.

best wishes [swingaloo]”

Don’t make it about you and your worries. Don’t make it about his health or his potential death. Just leave the door open for contact on his terms.

Being constructive for a moment, you could put a leaflet for a fall alarm in his letterbox.  Something like this

Plus a note saying that you will respect his wishes for privacy but if he needs anything he should not hesitate to ask you. 

You can’t really do anything more.
