OK so one of the air pockets I intend to retreat to and I have had an interest in it previously (dotted across this blog since 2006) is good old neuro science and neuro-surgery.

Yesterday I peeled potatoes and made a reasonable lamb shepherds pie while watching a film about brain surgery performed under local anaesthetic. I credit that film with vastly improving my cookery.

Plus it reminded me of the significance of vacuum in removing tumours and have to confess have always gotten great comfort from hoovering, except my one hoover calamity at age 5 that resulted in a split lip.
