Past lives, well we always wonder. When I was 50 I wasn't even aware eczema existed. Pain is a serious motivator in our search of knowledge, that's why you and others are on this site. If I hadn't educated myself I am not sure I would be alive today or at the very least free of eczema symptoms at this moment. For each of us, even with the same type of eczema we have different profiles with different responses to treatments. Many never get it figured out. Some types are more challenging and take more sacrifice.
I would guess it I had a past life it would have been humbly working off the land. I find that wrap around peace and wonder which completes me like when I am creating life in the outdoors. When I worked in the corporate world I with hassled commutes and incased in metal, concrete and stress and never could find the time for enough sleep.
What about your past life? My husband is convinced he was a Samurai Warrior, seriously. Fun to think about.
