Tip #1 Although you are not immortal you need those knees for another 50 years at least. At this rate you will destroy the cartilages and have arthritis. When your knees are swollen, take the bloody train back.
Tip # 2 reread tip # 1

That sort of heroism should be to rescue a maiden or destroying an enemy machine gun and mortar position pinning down your buddies! I have only been that brave a scant few times but it was required to rescue people and I was young and foolish!
