Your memory is good, Arthur - we did have a members’ meeting in Scarborough just over 5 years ago!
The young lady in your link obviously overcame her shyness and embarrassment to write an article about her hearing loss.
It’s perhaps a surprisingly common problem, affecting ~10 million people in the UK to some degree.
As you say, it often develops with age, so-called " sensorineural " hearing loss, in which the sensitive inner ear cells and " auditory " nerve taking signals to the brain become less effective.
The other main type of hearing loss is " conductive ", where sounds don’t pass properly from the outer ear to the inner ear ( commonest cause being ear wax ).
There are many other causes for both types of hearing loss - including genes, infections, injury such as perforated ear drum, and various illnesses. Exposure to loud noise - music, TV, or work-related - should be avoided.
