I have no idea what the numbers of my blood pressure are. It's always been 'on the low side' but no one's ever looked worried by it (although I did once get told they'd rather not let me donate blood that day). It was slightly amusing to be told "if you feel dizzy, eat some salty snacks, that might help get your BP up" at about the same time as the UK health bodies went "eek! salt BAD!" and suddenly even ready-salted-flavour crisps were being advertised as "now virtually salt-free".
