HI Ya, Dr. is concerned at 20. He has me doing multiple blood tests. one month, two months, 4 months and 6 mos. At which time we review. I fully agree on simple remedies. For now no casting. My gunsmith reminded me why "Mad as a Hatter" was common saying. The Hatters used Mercury. Lead is same problem.
I am taking this seriously.
Much obliged,
Max
