Your nail-biting habit can actually kill you!

A British man, who used to bite his nails constantly, has died due to his bad habit.

John Gardener had contracted a septic infection because of his habit and died while he was recuperating from a surgery to remove the tip of a finger, Metro.co.uk reported.

Gardener's doctor said that the former amateur football referee's fingernails were always in a 'bad condition' and he had lost a lot of sensation in them.

Gardener's mum said that she wouldn't want this to happen to anyone else's son and people should be aware of the potentially fatal results stemming from this habit.
