Topic: Dilemmas regarding the "Length" object

PDF Reference (p. 38) defines "Length" as "The number of bytes from the beginning of the line following
the keyword stream to the last byte just before the keyword
endstream.". However, the example PDF file (p. 978) gives the length of 73 for the following object, although it has only 44 bytes between the two keywords:

5 0 obj
<< /Length 73 >>
stream
BT
/F1 24 Tf
100 100 Td
(Hello World) Tj
ET
endstream
endobj

How does this happen? I've tried adding the number of bytes in the Font object:

7 0 obj
<< /Type /Font
/Subtype /Type1
/Name /F1
/BaseFont /Helvetica
/Encoding /MacRomanEncoding
>>

... but then the total is much higher than 73. So, what is really the "Length" object?
