But if you walk 30 minutes per day for 50 years of your life, you've already spent 9,125 hours walking, which is roughly equivalent to over a whole year of your life.

Thus, you're already down a year just from the walking. My motto about eating, exercising and death is that I'd rather enjoy my life now, than to have 5 more years of hell. Give me a nice, juicy steak any day of the week.

I heard some comedian put it this way:

"Hey, it's not like the three years you gain are 19, 20, and 21. It's 75, 76. and 77! I'd rather have my thirty minutes a day now!

I guess it depends somewhat on where you can walk.
I am fortunate enough to have fields and woods to walk through on the farm and wouldn`t want to give that up for anything.

well put.
