My dad's girlfriend went for past life regression years ago and she got into the mind frame of being a soldier at war and 're-lived' the experience of being shot in the thigh. After she came out of the experience she told the person who was helping her re-live it about her experience and they asked her if she had a birthmark in that area...low and behold she has a very odd grouping of moles in that exact area but nowhere else on her body. I found it very interesting.
The marks across my shoulders and just below my eyes point to the only possible conclusion: that I died via molten ash raining on my upper body and blinding me in a flash, the pain and confusion of said blinding leading me to slip and fall left leg first into pyroclastic lava flow
The only mark I ever had was on the inside of my right calf. That's long since faded, but my guess would be that I tripped and fell on a shard of glass and bled out. Sounds pretty typical me at any rate
