I picked up my flute* a few months ago and after a few tunes I had to sit down before I fell down; I remember being dizzy as a kid when I first started but it doesn't half seem worse when you've got further to fall! Though I'm hopeful that when I have money and start playing again (aiming for folk, instead of classical which frankly makes me faintly nauseous) my lungs will come into better condition than they were when I was living with two smokers.

*grade 4 then I gave up to get some A levels; I was clearly a substandard teenager compared to the rest of this lot if I couldn't get 5 A levels and be a virtuoso on a big pile of instruments at the same time

I got to the point on the flute where my teacher said if I did an exam it would be grade 4, but I was scared of doing an exam so I gave up the flute. Then I did A levels. I've just started picking up the flute again... it's rather fun.
