The elderly generally have a bad sense of smell and can't smell us. Our immediate families usually can't smell us so it's possible some people out there can't smell us as well. It's not until someone points out "it smells" that people notice and some still don't.
There are people on this site who have spouses that have commented their spouse can't smell their bo.
We alienate ourselves so as not offend anyone with our odor. But at the same time, we're leaving out those potential people who can't smell us and would like to be our friends.
It's tough but taking it a minute, an hr., a day at a time gets us through.
