Did you know that singing can stimulate your Vagus nerve. In result help you to relax and digest your foods much better and absorb more nutrient. But why National Anthem? Because:
It also bring joy to our hearts!
We all know the lyrics.
And we need to use all the power of our vocal cords so even a little more stimulation.
Here is a lovely video and I attached the lyrics here too in case a word is forgotten
Oh, say can you see
by the dawn’s early light What so proudly we hailed
at the twilight’s last gleaming? Whose broad stripes and bright stars
thru the perilous fight, O’er the ramparts we watched
were so gallantly streaming? And the rocket’s red glare,
the bombs bursting in air, Gave proof through the night
that our flag was still there. Oh, say does that star-spangled banner yet wave O’er the land of the free
and the home of the brave?
God bless you and God bless America! Sing to your health!
