One of my faithful visitors suggested I practise a little Irish dance if I want to remain lively and fit.
Excellent idea!
After all, one of my Irish ancestors, Máirebear Ó Mathúna,
a lady of very artistic temperament, was a great dancer
and I think I have inherited from her a certain natural predisposition for traditional Irish dancing.
I can give you one or two effective clues, if you want to try by yourselves.
First of all forget you have arms.
They are quite useless for Irish dance, You must pretend to have paralysed arms along your sides and it will be fine.
Opposite to that, you have to move your legs frantically, jumping as high as you can and striking your feet (or paws, it depends on whom you are) loudly on the floor.

I train in the basement, or else my neighbour,
Professor McLivet, would come running and shouting that there is earthquake....
