Do you take similar care walking over a floor in a modern house?
Because the same arrangement of floor boards exists there.

Chip floorboards are 22m or 38mm though, compared to 18mm for loftboards.

Remember you are talking about a 2' wide board adjacent and
interlocked with another, spanning one joist space - so there is no
reason for it to give at the edge.

I have certainly managed to crack the odd tongue off my loftboards

18mm is also ok for floors
