I would not punish yourself over this issue. I won't be swinging an axe like Mourad any time soon. What I do think needs to be taken into account is a persons physical condition. Apart from teen and twenty year olds we are all most likely in differing stages of "decomposition" and so the method employed will of necessity need to take into account those physical limitions.
Safety must be the key consideration as an axe can do an awfull lot of damage.
