Here's my tip: light bulbs, ice cream and lunch

Huh? you ask. Well, this isn't really my tip but a quote from neuroscientist, Daniel Levitin, who wrote the book " Successful Aging: A Neuroscientist Explores the Power and Potential of Our Lives."

Let me explain:
"When it comes to planning for quality of life in old age, Levitin recommends people ask themselves and their aging family members three simple questions posed by Joseph F. Coughlin, director of MIT's Agelab:

- Who will change my light bulbs?
Meaning, who can do the chores around the house that become difficult or dangerous as we age? Who can you call for help? If you need to pay someone to do those tasks, how much will that cost, and what services are readily available to you?

- What if I want an ice cream cone?
As people's social circles shrink in old age, Levitin said, it's a good idea to set up their lives in a way that makes it easy to walk down the street for an ice cream, a coffee, or a trip to the local pub. That's about leaving room for spontaneity, he said, and guarding against isolation.

- Who are you going to have lunch with?
"Are you living in a place, and have you arranged your life in such a way, that you have somebody to have lunch with once or twice a week?" Levitin asked."

What's your lightbulb, ice cream and lunch?
