Good for you; my 89-year old neighbor still mows his lawn (though last year his wife forbid him from cleaning the gutters). On the other hand, my in-laws, both also 89, have to use walkers to get around.
His fanfic bio indicates he’s 74 years old (or will be soon), and his daughter used to correct his spelling – too bad she apparently stopped. I couldn’t get past more than a few paragraphs of a story about Luann in college.
Many places the placards don’t get you free parking, they just get you closer parking.
