Well, Sam, I have not needed a flu shot since I've not gotten the flu since I was a kid due to a healthy diet and supplements. You are also the second person today that has recommended @timcliff as a witness. So I may just have to check him out.
This jump in SBD price is a nice little gift for the holidays. I started selling when it hit $7. Gotta answer Fortune's knock!
You said it. A perfect gift for Christmas ;)
And for sure you are right. Healthy diet for strong immune system is the best 'vaccine' we can have.
