It’s the best financial advice, covid is the marketing keyword to remind you, if you don’t spend every last penny in the wallet, you can never have a chance to spend that again. Spend until you drop you plebs!
This is not a good advice personally because you should only spend based on what you needs and what you can afford, beside if you die without money, you family will suffer later on. So my advice would be different, invest your money tell your family about it so when you're gone, they can still survive even without you. Its ok to spend but you have to limit it, and don't over spend especially if its beyond your budget.
