I think momentous is a little over-egging it. Momentous to me would suggest that the cause has been discovered and with a cause hopefully a cure / effective treatment. Momentous to me would mean people in wheelchairs walking again and people forced to leave work working again. I would say this has been another year where some progress has been made - but if anyone knows of other discoveries in the year - let's list them.
Well, Bromley, from my point of view, I hadn't quite got into a wheelchair, but now thanks to doxycycline and so on, prescribed in the first instance by my husband, a microbiologist, I won't have to. I am also now painting and therefore making a living again. The road is continuing its route upwards, which suits me fine, because I have always found climbing a steep hill easier than coming back down.
So, best wishes to everyone for the coming year,
