48 must be an common age for us old'uns. There's a 20 year old in me, but my body won't let her out to play!(I'm the mother of 2 teenage girls, which is enough to age anybody, and a lad of nearly 21).
To be honest, having seen the age of some of the younger 'catters, I am amazed at how articulate and mature they are. I had no idea there were people of such tender years with us. Or is that just me showing my age? There is so much talent in the young musicians who are emerging these days. I sometimes wonder what their own offspring will be playing like!
