The definition of death

Ask you all what's the definition of death ,
and some people would swear it's breathing your very last breath,
 but death to me means you can no longer feel ,you can no longer hurt and you can no longer heal ,
death to many puts fear in our eyes,
 but I never fear death I just fear it's disguise,
 so for all who fear death it's not  death that  you don't fear,
 it's having our hell to which both isn't clear
