Might as well have a thread on what oil is the best oil... If you ask 10 people, you will get 11 different answers.I have read many times to take at 62 and invest it....

FWIW, I think it depends on everyone's personal circumstances.
I think @JeffKeryk makes an excellent point with the $5 bill analogy. I will share my perspective. The time value of money is difficult to overcome, so taking the money earlier tends to pay off. The tipping point can easily be calculated to find a best fit answer. Unfortunately, life expectancy is the biggest unknown.
