One 'tuner', who has thankfully since= retired, was quite fond of pulling top C up to the E fl above.= As our hearing rolls off as we age, we prefer the treble stretch= to be wider. I don't know why, but its a conclusion I've drawn,= tuning from 22 years of age to 51.</DIV> <DIV><BR></DIV> <DIV><FONT color=#0000ff>Speaking of deteriorating faculties,= just as an aside.</FONT></DIV> <DIV><FONT color=#0000ff><BR></FONT></DIV> <DIV><FONT color=#0000ff>In my home town out west from Sydney 350= miles, an elderly (80+) man visited the local GP recently and= complained about his aches and pains and the difficulty he was= having pushing the lawn mower.
