Last year I changed my diet to a super healthy - fruits, veggies, juicing, salads, nuts, fish, lean chicken, no wheat, no alcohol
/drugs/smoking, along with working out and stuff. So I assume my immune system would be "healthy". I haven't had a cold for several years (no vaccination). Mentally, I had some depression because of psoriasis but it was manageable.
2 months ago I had a heart procedure - WPW ablation because I was experiencing heart arrythmia issues.
