To be honest I've never seen a better cholesterol profile than yours. If there's one thing in life you don't need to worry about, it's your cholesterol! :)
Just one question? What's the secret? How did you get so perfect cholesterol values?
Your numbers are perfect, I don't think you should go any lower on your LDL unless you have heart disease or some major risk factors. Also, your HDL is great as well. You can increase it with Omega 3 fatty acids like fish oil. Also, staying natural with fruits and veggies and staying away from processed foods will help your LDL if you do need to lower it.
Overall, I think your numbers are great, nice job!
