Old people should be more adventurous

When you are old you don't have to worry about what your boss thinks - you are retired. You don't have to worry about what your parents think - they are dead. You don't even have to worry what society thinks - you are allowed to be a little eccentric. So how come most old people dress in the most boring outfits and don't do anything more exciting than lawn bowls? I plan on starting a rock band when I'm 80. I am going to get around in a pink tux and have a white snake draped around my shoulders. Hopefully I can grow one of those curly moustaches by then.
