Sometimes when I bathe I find mystery bruises that often leave me wondering what did I bump into, or how did this happen?

When I brought up the marks, someone suggested to me that it could be certain supplements that I take.  So I did a little research on-line and with my doctors and found out that in your 30's and 40's the bruising could come from things like:

Aspirin - which causes blood from your vessels not to clot as easily.

Fish oil, Omega 3, Gingko, Ginger, & Garlic;  These dietary supplements can increase bruising cause they also have a thinning affect.

If you are prone to bruising easily, you should watch your sun exposure cause it can weaken the blood vessels walls and damage the skin.

In your 50's the capillaries age & become faragile.  Over time the tissues that support the vessels weaken as well. The protective fatty layer that usually protects tissue breaksdown, leaving you more suseptable to bruising.

In my case it was jumping on the Fish Oil bandwagon - along with my regular meds.  So before you go crazy on supplements, you should ask your doctor!
