I beg to differ..The numbers are important in the world we are living in.
If the numbers are small, the sickness are not well known, there are no researchers getting interested in, there is no medical field journal publishing research in that matter.
On the other side, few numbers do not create a market, if the sickness is not lethal nobody pays attention to those who are sick, no research funds are generated. Thus again no researcher gets interested in it as there is no fund to be used in double-blind experiments, staff expenses, medical equipment etc.
A few examples: wobblers is a support group for people who are cursed with bilateral vestibulopathy. These people are poisoned by modern medicine (aminoglycoside antibiotics). Their vestibular system are knocked down permanently. They cannot see clearly, they have oscillopsia i.e jumping vision, they cannot walk and hardly can function. Their numbers are so small -probably less than 5000 around the globe- that no research is "profitable"
moreover the modern medicine's current focus is 'lethality' and 'epidemics'. Ebola is the perfect example. Look at all the fundraising and public campaigns. The 'life quality' perspective is not very popular in medicine. That's why, in my opinion, we get "get used to it" a lot.
T is indeed very common, more common that we think it is, but the severity is the key. We suffer. Myself, one of my ears is paralysed, does not hear well, the things it hears it hears wrong, it makes its own noises for every sound it hears, and it disturbs my vestibular system.
It is at least encouraging for us that numbers are inflated to include those with acute T. We can therefore at least satisfy 1 of the criteria modern medicine is interested in: Market.
Small market+no lethality+no epidemics: humanity may even find a unified theory of gravity or time travel but still no cure for that disease.
