1. plausible
2. I punch trees, but fists too strong, could be lie
3. truck. no way. momentum of truck... p=mv, say truck is 4536 kg, say it was travelling at 16.7ms (60kmh), 16.7 X 4535 = 75,751.2kg ms-1. The change in momentum on a human's body (impulse) that a human can survive is 2000-3000 kg ms-1. You were hit with an impulse of 75000 kg ms-1, give or take 10 000. If this is true you're superman.
So I think, it's number 3 that's a lie.
