Strengthen the immune system - prevent colds and flu

I've had no flu for 4 months, no cold, just had a cold for a short time. Even though I work in the middle of a sea of bacilli. I am surrounded daily by sniffing noses and coughing.

I am not vaccinated, nor do I take any medication to prevent it. Reason:

Every 2 days I squeeze out an orange, half grapefruit and half a lemon. That will be drunk immediately.

When I read that z. If you want to help hot lemons or mixed with honey so that it is not so sour, I can only say, if you heated lemon or honey, vitamins and healthy ingredients are lost. Therefore prefer to drink pure.

Conclusion: I do not need a flu shot, no medication and feel well.
