They would make spinos awkward and slow walkers, but might have  been an adaptation for life in the water.

它们会让斯皮诺斯变得笨拙且行走缓慢，但可能是对水中生活的适应。

And to add insult to injury, the study found not only did slower walkers' bodies age more quickly, their faces looked older and they had smaller brains.

雪上加霜的是，研究发现，走得慢的人不仅身体衰老得更快， 而且他们的脸看起来更老， 大脑也更小。

The BBC's Philippa Roxby writes that tests on 1,000 people from New Zealand born in the 1970s found that slower walkers tended to show signs of " accelerated ageing" .

BBC 的菲利帕·罗克斯比 (Philippa Roxby) 写道，对 1,000 名出生于 1970 年代的新西兰人进行的测试发现，走路较慢的人往往会出现“加速衰老”的迹象。

This led them to assume that pterosaurs  would've been skilled flyers, but slow walkers that would've had to drag themselves along  the ground on their bellies to get around on land.

这导致他们假设翼龙是熟练的飞行者，但行走缓慢， 必须用肚子在地上拖着自己才能在陆地上四处走动。
