• Bubble construction is often used for things other than tennis.
• While considerable modern liberty may have been taken during the reconstruction of Stonehenge, it is probably very similar to how it would have looked at its peak. I think it is safe to say they didn't complete any trilithons that did not, at some time in the past, stand. This is very different from Williamsburg, where, while plenty of thought was given to make the buildings appear appropriate, there are many anachronistic embellishments to the construction.
• I'm unsure as to the veracity of the whole 'Zinc causes loss of sense of smell' thing. Most of the lawsuit claims are tied specifically to the use of sprays or gels. Since a cold itself is one possible cause for loss of sense of smell (anosmia), these things seem difficult to verify.
