Attached to your hair? Probably not as much as Cen Yingyuan is to hers.
The 44-year-old, from the Guangxi Province of China, hasn't cut her hair in 11 years and admits she is "addicted" to her mane.
Cen even saves every strand that falls out, which for those who are curious, amounts to a 50-gram haul every year.
"I have saved the hair for 11 years, and I am quite addicted to it," said Cen. "In the summer time my hair flows in the wind. I feel so free.
Standing at 1.53m in height, Cen's locks trail on the ground with a stunning length of 1.84 metres - and she claims that her hobby is catching on.
"The young people in the neighborhood are now saving their hair also, thanks to my example."
Cen says she has been offered up to 20,000 Yuan (£2,000) in exchange for her pride and joy and while she has turned down the offers, she did bring herself to part with her collection of fallen strands in 2011.
Unsurprisingly, maintenance is a pain. The mane takes over an hour to wash and then half a day to dry. Cen uses beer to keep it shiny and is proudly showing no signs of grey.
"If the hair started to turn grey, I'll dye it all white, making myself have another look," she added.
AND HAIR-JACKING HITS SOUTH AFRICA...
People in Johannesburg are being mugged...for their dreadlocks.
Cut-and-run thieves are targeting long locs in the street, using anything from knives to broken glass to hack off the hair, according to the BBC.
The sudden demand for dreadlocks stems from a new technique called crocheting, which requires human hair.
Jake Maseko said that he used to see people selling dreadlocks on the streets and didn't know where the hair came from, until he became a victim:
They had a knife and cut off my hair with scissors. I still feel pain when I think about that night.
Last month, Zimbabwean national Mutsa Madonko, who had spent 10 years cultivating his locs, had his hair shaved off outside a Johannesburg night club.
