DEAR HELOISE: Recently, I watched a flight attendant open up cans using a credit card under the tab. After I returned home, I had a black bean can to open and tried using the credit card to pull the tab up. No broken fingernail or sore fingers! I would guess that people who have arthritis would find this to be an easy way to open cans.

DEAR HELOISE: I was having trouble remembering to take my key fob when I left home until my husband put a safety pin on my fob. I just pin the fob to my blouse or other garment (or inside a pocket). I never forget my key fob now. I hope this will help some other forgetful person.

DEAR HELOISE: I’ve been a hairdresser for over 18 years, and there are a few things that I’d like to remind women of when they make an appointment at a beauty salon. First, this is not a hobby; it’s a job. It’s how I pay my bills and feed my kids. I work hard and stand on my feet all day. So, please remember:

● To show up on time. Most hairdressers will make you reschedule if you are 15 minutes late.

● Do not cancel at the last minute, and no, I will not call a client and ask them to reschedule because you want their time slot.

● Don’t ask for a discount / samples or any of my equipment, especially my scissors.

● If your friends also come to me, please don’t ask me questions about their personal lives. Even if I know the latest gossip, I won’t share it.

● Referrals are welcome and appreciated, but I won’t pay clients to refer people. However, I will do a great job on their hair!

● Next (and this is awkward), bathe or shower before you come.

● Lastly, if you came in for a haircut, highlights, or any other service, I allow a certain amount of time for your appointment. If you need or want additional services, you’ll have to make a separate appointment. My next client is sitting in the waiting area, and it’s not fair to keep them waiting. Thank you.

DEAR HELOISE: Since I am on a low-carb, low-sugar diet, jellies and jams are off-limits to me. But once in a while, a guy has to have a peanut butter and jelly (or jam) sandwich. Peanut butter on a no-net-carb tortilla is OK.

For my fruit spread, I take several frozen blackberries and thaw them out in the microwave. If they aren’t sweet enough, I add a teaspoon of monk fruit and artificial sweetener. It is very satisfying and has few carbs.
