My kids (girls, 9 and 12) treat my VHF61 with some respect, as I still haven't really sorted it out and hence the back is not screwed on. So I told them 'stick your hand in there and you'll die'. They like to regale their friends with this sober instruction when they come round (perhaps I should add I don't rely on other people's kids ability to take instruction like I rely on my own
).
