is there a threshold age where we stop being adventurous? like adventurous with food for example?

took my parents to dinner last night and my mum ordered a soft-shelled crab salad. the crab was lightly battered and deep fried. the idea was to just eat the large pieces it was cut into with the papaya salad it was with, shell and all. it was so delicious!

but it freaked my mum out and she was trying to tease out the flesh like how crabay be served when its boiked/smoked.

im pretty sure mum went home hungry.. she was too polite to say so
