Let's say I have that $62 million and I invest the money in the 10-year UST at 1.75%,
$62,000,000 * 1.75% = $1,085,000 per year
$1,085,000 / 12 = $90,416.66 per month
I would say that I would live VERY COMFORTABLY with $90,416.66 per month (or, about $3,000 per day).
And, I would still have the original capital of $62 million, untouched!
