Hahahaha, when you were a boy. That was decades ago and you can't possibly go back.
I love the fact of not giving up instead devising a means to keep pushing.

You see, this is the hardest part about being overweight: Perhaps you remember what you could do when you were a kid and now that you can't do that anymore it is exceptionally frustrating. Perhaps you are dillusional about how you are definitely going to suck at anything cardio when you have essentially been sitting on your ass and drinking beer for the past 5 years. Rather than face embarrassment you just give up. I didn't give up and instead decided to come up with a plan: leave the stopwatch at home and simply try to do 12 laps the next day.
