Weak Fire, Strong metal

[myfs_122065]

Hi Astrologer,
My friend is born with a weak yin fire self element, with many metal (and earth dog) in his pillars. Thus, is it the follo the Leader destiny? His spouse home is earth ox (signified by water).
I read a book that if he undergoes the fire/wood luck pillars there is a possibility of accidents resulting in death. Could it be prevented, and is that really the case?
From birth to 35, his luck pillars are mstly water and earth. However, after 36, there is strong wood and wood/fire. I am quite afraid for him. What does it mean?
As for me, I am strong metal, with my spousal home in fire. So, does that mean he might be good for me, but I am bad for him? Both of us lack a significant amount of wood in our charts.
Many thanks for your response.
