Better put a tread mill on board or you’ll see a pulmonary embolism every few flights.
Obviously this route is a heavy Business oriented route so it would seem that most people will be of working age. So hopefully they’ll be in good health and able to handle long fatiguing flights. Its sad but on some leisure routes I’ve seen older people that want to go back to the “old country” one more time, end up expiring before they get there.
