Question from Chris - Average height

What was the average height around this time period? I know most Medieval/Tudor era knights were expected to be like, over 6, preferably like, 61 or 62, or taller. The peasants and surfs probably were quite a bit shorter, and the ladies, (unless she was aristocratic/wealthy) werent quite as tall as the men. So, on average, how tall were most average citizens? (Both male and female). A good estimate from someone, or another blogger would be helpful. Thanks.

Question from Glenn - Appendectomies

How were appendectomies performed? If I were to need my appendix removed, in this time, how painful or dangerous would it be? Would it have been any more dangerous and painful, then, than it is now? Did people then even call them that?

Question from Lorraine - Milestone birthdays

My question is about milestone birthdays. Were birthdays, (in a child or adult's life) such as 10th, 13th, 16th, 18th, 21st, 30th; etc,.. considered as important back then, as they are now? Did people celebrate these ages the same way we do now? Were there any traditions that people had for those who finally turned a certain age? Lastly, did people see getting older as a good thing or a bad thing?

Question from David - Time travel 'what ifs'

My question is about time travel. As a huge time travel genre fan, I was wondering what would ( probably) happen if I were to travel back to this era, and bring with me some modern day stuff, like, iPads, computers, modern day foods for them to try, a TV set; etc,.. Or if a Tudor era gent/lady were to travel forward to this time, and experience and find out about what life is like now. Would they be shocked, appalled, or (happily) fascinated?
