I had the distinction on my report card when I graduated 4 years of technical school never missing a day. As far as injuries I had to retire from racing bikes, and sleds due some serious mishaps by the time I was 39. Took me a full year to recover from one bad chitter. As you age, you may still feel 18, but your body says different.Same here. I never missed a day of school or work for being sick. Only sports injuries. My Wife had the kung-flu twice and I never got it.
