Hi jacky1st2016 - I've just edited your original post because I don't know how public what you mentioned is.
I have also asked a few people to reach out and check that he is ok. His English is most excellent, I have the fortune of meeting him at Essen in 2016, 2018, and last year in 2022.
I'm not sure he'd be happy with you passing his phone number on, but I'd be happy to send him a message and check that everything is ok.
