As commented by the beautiful flight attendant &amp;#8220;this used to be an old man&amp;#8217;s drink, but more women are drinking this because its healthy.  It&amp;#8217;s made using sweet potatoes&amp;#8221;.  There you have it&amp;#8230;I&amp;#8217;m either an old man or young woman&amp;#8230;but that&amp;#8217;s the first #sweetpotato I&amp;#8217;ve had with a quality kick.  #travel #anaairlines #japan #shochu #spirits #instagood
